Competition Law and Competition Issues in Layered Digital Ecosystems

1. Introduction

A layered digital ecosystem is a digital environment in which several interconnected technological layers work together to provide products or services to users. These layers may include:

Hardware layer – smartphones, computers, smart devices and servers.

Operating-system layer – Android, iOS, Windows and other operating systems.

Cloud and infrastructure layer – cloud computing, data centres and application infrastructure.

Platform layer – app stores, marketplaces, search engines and social-media platforms.

Application layer – apps, software and digital services.

Data and analytics layer – user data, algorithms, artificial intelligence and analytics.

Payment and identity layer – digital wallets, payment systems, authentication and identity services.

Competition problems arise when a powerful undertaking controls several layers simultaneously and uses its position in one layer to influence competition in another.

For example, a company controlling an operating system may also operate an app store, payment system, advertising service and search engine. It may then have the ability to favour its own services or impose conditions on competitors.

Therefore, competition law must examine not only competition within an individual market but also competition between connected layers of the digital ecosystem.

2. Meaning of Layered Digital Ecosystems

A layered digital ecosystem can be understood as a multi-level digital structure in which different technological and commercial functions are interconnected and controlled by different or sometimes the same businesses.

Simplified structure

Hardware

↓

Operating System

↓

App Store / Platform

↓

Applications

↓

Data / AI / Advertising

↓

Payments and Other Digital Services

The layers may be technically separate but economically interconnected.

A firm controlling an upstream layer may therefore affect competition in downstream markets.

3. Main Characteristics

3.1 Interdependence

The layers depend upon one another.

For example:

apps depend upon operating systems;

applications may depend upon app stores;

digital advertising depends upon data;

payment applications may depend upon access to operating-system functions.

This interdependence can create opportunities for exclusionary conduct.

3.2 Network Effects

Digital platforms often become more valuable when more users and businesses participate.

For example:

More users → more developers → more applications → more users.

This can create a self-reinforcing competitive advantage.

3.3 Data Advantages

A company operating across multiple layers may collect data from several sources.

For example:

search data;

location data;

transaction data;

app usage data;

advertising data;

device data.

Combining these datasets may create a significant competitive advantage.

3.4 Vertical Integration

A single company may control several layers.

For example:

Operating system + app store + payment service + advertising + cloud service

Such vertical integration is not automatically unlawful, but it can create competition concerns when the integrated company uses control of one layer to restrict competitors in another.

3.5 High Switching Costs

Users and businesses may find it difficult to move from one ecosystem to another because they have:

stored data;

purchased applications;

subscriptions;

digital identities;

contacts;

accumulated content;

business relationships.

Switching costs can make market entry more difficult.

4. Competition Law Issues in Layered Digital Ecosystems

4.1 Leveraging Dominance Across Layers

One of the most important concerns is leveraging.

A dominant undertaking in one layer may use its market power to obtain an advantage in another layer.

Example

Suppose a company has a dominant operating system.

It also offers its own:

browser;

payment service;

search engine;

music application.

If it imposes restrictions preventing competing services from accessing important operating-system functions, competition in downstream markets may be weakened.

This can raise concerns under abuse-of-dominance provisions.

5. Self-Preferencing

Self-preferencing occurs when a platform gives preferential treatment to its own products or services.

For example:

A platform owns both:

the platform itself; and

a competing application.

It may place its own application at the top of search results or give it preferential access to platform functionality.

The concern is that the platform may act simultaneously as:

market operator + competitor + gatekeeper.

This can distort competition.

6. Tying and Bundling

A dominant digital company may require users to obtain one service together with another.

For example:

Access to an operating system may be linked to:

a search service;

browser;

payment service;

cloud storage;

advertising service.

Tying can be particularly significant in digital ecosystems because control over one layer may provide immediate access to users in another layer.

7. Exclusive Dealing

A platform may impose conditions requiring businesses to use its ecosystem exclusively.

For example, an application developer may be required to:

use a particular payment system;

avoid competing platforms;

use a particular advertising system;

accept contractual restrictions concerning alternative distribution channels.

Such restrictions can make entry or expansion by competitors more difficult.

8. App Store Restrictions

App stores are particularly important layered ecosystems.

An app-store operator may control:

admission of applications;

ranking;

technical standards;

payment systems;

commissions;

access to users;

advertising.

Competition concerns may arise where the app-store operator:

imposes excessive commissions;

prevents alternative payment systems;

discriminates between applications;

favours its own applications;

restricts alternative distribution channels;

prohibits communication with customers about alternative purchasing methods.

9. Interoperability Restrictions

Interoperability means the ability of different technological systems to work together.

A dominant ecosystem may restrict interoperability with competing products.

Examples include restrictions concerning:

APIs;

data portability;

messaging;

payment systems;

authentication;

cloud services;

operating-system functionality.

A refusal or restriction may become a competition concern where access to the relevant facility is important for effective competition.

10. Data Concentration

Data is an important competitive input in digital markets.

A company controlling several layers may collect data from each layer.

For example:

Search data + location data + shopping data + payment data + advertising data

can create a powerful information advantage.

Competition concerns may arise where:

competitors cannot obtain comparable data;

data is used to disadvantage competitors;

data from one market is combined with another market;

customers are prevented from transferring their data;

data is used to strengthen an existing dominant position.

11. Algorithmic Competition Problems

Layered ecosystems increasingly rely on algorithms.

Algorithms may determine:

rankings;

prices;

recommendations;

advertising;

access;

visibility;

search results;

fraud detection.

Potential problems include:

algorithmic discrimination;

algorithmic self-preferencing;

coordinated pricing;

exclusion of competitors;

manipulation of rankings.

The use of an algorithm itself is not unlawful. The competition-law question concerns how the algorithm is used and its effects on competition.

12. Killer Acquisitions

Large digital ecosystems may acquire emerging competitors before they become serious competitive threats.

A large platform may acquire:

an AI startup;

a data company;

a social-media application;

a payment startup;

a cloud technology provider.

Even where the acquired company's current turnover is small, the transaction may have substantial future competitive significance.

This creates challenges for traditional merger-control thresholds based heavily on turnover.

13. Network Effects and Market Entrenchment

Network effects may reinforce the position of an established ecosystem.

A simplified cycle is:

More users → more developers → more applications → greater ecosystem value → more users

A new entrant may therefore face a significant disadvantage even if its technology is innovative.

Competition authorities must therefore examine whether network effects are:

contestable;

reinforced by exclusionary conduct; or

simply the result of superior competition.

14. Gatekeeper Power

A firm controlling an important digital layer may become a gatekeeper.

Examples include companies controlling:

app stores;

operating systems;

search engines;

digital advertising infrastructure;

cloud infrastructure;

payment systems.

Gatekeeper power may allow the firm to determine:

who obtains access;

on what conditions;

what products are visible;

how transactions occur;

what data can be accessed.

This can create significant competition concerns.

15. Predatory or Strategic Pricing

Digital ecosystems frequently use:

free services;

zero-price services;

discounts;

subsidies;

bundled services.

Traditional price-based competition analysis may therefore be insufficient.

A company may provide one service for free while recovering costs from:

advertising;

commissions;

data;

subscriptions;

another layer of the ecosystem.

Competition authorities may therefore examine the overall ecosystem economics rather than looking at only one price.

16. Margin Squeeze

A vertically integrated digital company may operate:

an upstream infrastructure layer; and

a downstream competitive service.

If it charges competitors a high upstream price while maintaining a low downstream price for its own service, competitors may face a margin squeeze.

This can make downstream competition difficult even when competitors technically have access to the upstream service.

17. Exclusive Access to Data and Technology

A dominant ecosystem may restrict competitors' access to:

APIs;

technical standards;

datasets;

interoperability tools;

authentication systems;

payment infrastructure.

Where the restricted input is commercially important, such conduct may create exclusionary effects.

18. Privacy and Competition

Privacy and competition are increasingly interconnected.

A digital service may compete not only on price but also on:

privacy;

data protection;

security;

transparency.

A dominant undertaking could theoretically reduce privacy quality without users easily switching because of high switching costs.

Competition authorities may therefore consider quality dimensions, including privacy, when analysing digital markets.

However, competition law does not automatically treat every privacy violation as an antitrust violation. The relevant conduct must have a competition-law connection.

19. Dark Patterns and Consumer Lock-In

Digital ecosystems can use interface designs that make switching difficult.

Examples include:

complicated cancellation processes;

default settings;

difficult data export;

confusing consent mechanisms;

automatic renewal;

obstacles to changing platforms.

These practices may reinforce ecosystem dependence.

Where such conduct contributes to exclusionary effects, it may become relevant to competition analysis.

20. Relevant Indian Competition Law Framework

In India, the primary legislation is the Competition Act, 2002.

Important provisions include:

Section 3

Deals with anti-competitive agreements.

Relevant issues may include:

exclusive agreements;

restrictive arrangements;

agreements between competitors;

vertical restraints.

Section 4

Deals with abuse of dominant position.

Relevant forms of conduct can include:

unfair or discriminatory conditions;

unfair or discriminatory prices;

limiting production or technical development;

denial of market access;

tying;

leveraging dominance from one relevant market into another.

Section 4 is particularly relevant to layered digital ecosystems.

Section 5

Deals with combinations, including mergers and acquisitions.

It is relevant to acquisitions involving:

digital platforms;

AI companies;

data-driven businesses;

technology startups.

Section 6

Deals with regulation of combinations.

Digital acquisitions may create difficult questions where the target has substantial future competitive potential despite limited present turnover.

21. Important Case Laws

Case 1: United States v. Microsoft Corp.

253 F.3d 34 (D.C. Cir. 2001)

Facts

Microsoft was found to have engaged in exclusionary conduct concerning the Windows operating-system ecosystem, particularly in relation to competing browsers.

Principle

The case demonstrates how control over an important technological layer can be used to restrict competition in an adjacent layer.

Relevance

It is highly relevant to layered digital ecosystems because an operating system can function as an important gateway to downstream applications and services.

22. Case 2: Google Shopping

European Commission Decision, Google Search (Shopping), Case AT.39740; General Court, T-612/17

Facts

Google was found to have favoured its comparison-shopping service in its general search results.

Principle

A dominant platform's treatment of its own downstream service can raise concerns where its conduct reduces the ability of competing services to compete effectively.

Relevance

The case illustrates the self-preferencing problem in a layered digital ecosystem:

Search layer → comparison-shopping layer

23. Case 3: Google Android

European Commission Decision, Google Android, Case AT.40099; General Court, T-604/18

Facts

The case concerned Google's contractual practices relating to Android, including arrangements concerning search, browsers and app distribution.

Principle

Contractual restrictions and tying arrangements involving a dominant digital ecosystem may restrict competition in adjacent markets.

Relevance

Android demonstrates how an operating-system layer can influence:

search;

browsers;

app distribution;

mobile services.

It is therefore a classic example of layered ecosystem competition issues.

24. Case 4: Google Search (AdSense)

European Commission Decision, Google Search (AdSense), Case AT.40411

Facts

The European Commission examined contractual restrictions concerning online search advertising.

Principle

A dominant platform may not use contractual arrangements to restrict competitors' access to important distribution opportunities where such conduct produces exclusionary effects.

Relevance

The case demonstrates the interaction between:

search → advertising → publishers → advertisers

These interconnected layers can reinforce market power.

25. Case 5: Intel Corp. v. European Commission

C-413/14 P

Facts

The case concerned Intel's rebates and their potential exclusionary effects.

Principle

The Court of Justice emphasised the importance of analysing whether allegedly exclusionary rebates are capable of restricting competition and, where the undertaking provides relevant evidence, examining the economic effects.

Relevance

The principle is useful for layered ecosystems where a dominant company may use discounts or incentives to influence participants in adjacent markets.

It shows that competition analysis should consider the actual economic mechanism of exclusion, rather than relying solely on formal contractual labels.

26. Case 6: Hoffman-La Roche & Co. AG v Commission

Case 85/76

Facts

The case involved exclusivity arrangements and loyalty-inducing rebates by a dominant undertaking.

Principle

A dominant undertaking has a special responsibility not to allow its conduct to impair genuine competition.

Relevance

In digital ecosystems, exclusivity arrangements can potentially be used to lock developers, suppliers or distributors into a particular ecosystem.

The case therefore provides an important foundation for analysing ecosystem-based exclusivity.

27. Case 7: United Brands v Commission

Case 27/76

Facts

The case concerned the determination of dominance and abusive conduct by United Brands.

Principle

The judgment is important for understanding:

relevant-market analysis;

dominance;

market power;

exclusionary and exploitative conduct.

Relevance

Digital ecosystems frequently involve difficult questions concerning how the relevant market should be defined.

A digital company may operate across multiple related markets, making traditional single-market analysis more complicated.

28. Case 8: FTC v. Staples, Inc.

970 F. Supp. 1066 (D.D.C. 1997)

Facts

The proposed merger between Staples and Office Depot was challenged because of concerns about reduced competition in the sale of office supplies.

Principle

Market definition and competitive effects are central to merger analysis.

Relevance

The case is relevant by analogy to digital ecosystems because authorities must identify the competitive constraints that would actually be lost following consolidation.

In digital markets, the relevant question may involve not merely current sales but also:

innovation;

data;

platform access;

future competition.

29. Case 9: Airtours plc v Commission

Case T-342/99

Facts

The European Commission had prohibited a proposed merger based on concerns regarding collective dominance.

Principle

The case is a major authority concerning coordinated effects and the conditions under which a concentrated market may facilitate coordinated behaviour.

Relevance

Layered digital ecosystems can have:

few major firms;

high transparency;

algorithmic monitoring;

similar pricing systems;

strong network effects.

These characteristics can make coordinated-effects analysis particularly important.

30. Case 10: FTC v. Qualcomm Inc.

969 F.3d 974 (9th Cir. 2020)

Facts

The case concerned Qualcomm's licensing practices in the mobile-device technology sector.

Principle

The judgment illustrates the importance of carefully identifying the relevant antitrust duty and competitive effects when dealing with vertically related technology markets.

Relevance

Mobile ecosystems often involve several interconnected layers:

chip technology → device manufacturers → operating systems → applications → services

The case therefore provides useful material for understanding competition problems in technologically layered industries.

31. Competition Risks in Layered Digital Ecosystems – Summary Table

32. Economic Effects

Layered digital ecosystem practices can affect competition in several ways.

32.1 Reduced Entry

New companies may find it difficult to enter because they need access to several layers simultaneously.

32.2 Reduced Innovation

If competitors cannot access important technological infrastructure, innovation may decline.

32.3 Higher Dependence

Businesses may become dependent upon a dominant ecosystem.

32.4 Reduced Consumer Choice

Consumers may receive fewer competing products and services.

32.5 Higher Switching Costs

Users may remain with an ecosystem even when alternative products are available.

32.6 Data Advantages

The incumbent may use accumulated data to improve its products and strengthen its market position.

33. Are Layered Ecosystems Always Anti-Competitive?

No.

Layered ecosystems can produce substantial efficiencies.

They may provide:

better integration;

improved security;

lower transaction costs;

interoperability;

better user experience;

faster innovation;

lower prices;

improved reliability.

Therefore, competition law should distinguish between:

legitimate ecosystem integration

and

exclusionary ecosystem control.

Vertical integration itself is not automatically illegal.

34. Role of Competition Authorities

Competition authorities should examine:

Relevant market definition.

Market power.

Network effects.

Switching costs.

Data advantages.

Interoperability.

Access conditions.

Self-preferencing.

Exclusivity.

Tying and bundling.

Effects on innovation.

Entry barriers.

Consumer welfare.

Dynamic competition.

Potential future competition.

35. Possible Remedies

Where anti-competitive conduct is established, authorities may consider remedies such as:

Structural Remedies

divestiture;

separation of businesses;

limits on acquisitions.

Behavioural Remedies

non-discrimination obligations;

interoperability requirements;

data portability;

restrictions on exclusivity;

transparent ranking;

fair access requirements;

restrictions on self-preferencing.

Merger Remedies

blocking transactions;

divestiture;

access commitments;

licensing commitments;

interoperability commitments.

The appropriate remedy depends upon the particular competitive harm.

36. Challenges for Competition Authorities

36.1 Rapid Technological Change

Technology may change faster than legal investigations.

36.2 Multi-Market Operations

One company may operate simultaneously in many interconnected markets.

36.3 Zero-Price Services

Traditional price analysis becomes difficult where users pay nothing.

36.4 Difficult Market Definition

The boundaries between search, advertising, data, cloud and platform services may overlap.

36.5 Data as a Competitive Asset

Traditional market-share measures may not capture the importance of data.

36.6 Innovation Competition

The most important competitive harm may occur through reduced future innovation rather than immediate price increases.

37. Indian Competition-Law Perspective

The Indian digital economy increasingly contains interconnected ecosystems involving:

e-commerce;

digital payments;

smartphones;

app stores;

online advertising;

cloud computing;

food-delivery platforms;

mobility platforms;

digital financial services.

The Competition Commission of India therefore has to examine not merely the size of an individual digital service but also the strategic relationships between connected markets.

Particularly important concepts include:

dominance;

leveraging;

denial of market access;

tying;

exclusive agreements;

discriminatory conditions;

network effects;

data advantages;

platform neutrality;

interoperability.

38. Difference Between Traditional and Layered Digital Markets

39. Important Legal Principle

The central competition-law principle is:

Control over one digital layer should not automatically become a mechanism for unfairly restricting competition in another layer.

At the same time, competition authorities must not treat every successful integrated ecosystem as anti-competitive.

The critical questions are:

Is the undertaking dominant?

What is the relevant market?

What layer is controlled?

What adjacent layer is affected?

What conduct connects the two layers?

Does the conduct foreclose competitors?

Are there legitimate efficiencies?

Can competitors realistically enter or expand?

What is the effect on innovation and consumer choice?

40. Conclusion

Layered digital ecosystems represent one of the most important modern competition-law challenges.

Their competitive significance arises from the interaction of:

platforms;

operating systems;

hardware;

applications;

cloud infrastructure;

data;

algorithms;

advertising;

payments;

artificial intelligence.

The principal concern is not simply that a company operates several layers. Rather, the concern arises when control over one layer is used to foreclose competitors, restrict access, discriminate against rivals, create artificial switching costs, or extend market power into adjacent markets.

Cases such as Microsoft, Google Shopping, Google Android, Google AdSense, Intel, Hoffman-La Roche, United Brands, Airtours, Staples and Qualcomm provide important principles for analysing these issues.

For modern competition law, therefore, the appropriate approach is increasingly ecosystem-oriented: authorities must consider not only competition within individual markets but also how power, data, technology and contractual control move from one digital layer to another.

Quick Revision Points

Layered digital ecosystems consist of interconnected technological and commercial layers.

Examples include hardware, operating systems, app stores, applications, cloud, data and payments.

Vertical integration is not automatically anti-competitive.

Self-preferencing is a major ecosystem concern.

Tying and bundling can extend dominance between layers.

Exclusivity can increase ecosystem lock-in.

Network effects can reinforce market power.

Data concentration can create competitive advantages.

Interoperability restrictions can hinder competitors.

App stores can act as important gatekeepers.

Zero-price services require non-price competition analysis.

Killer acquisitions can eliminate potential future competitors.

Section 3 of the Competition Act, 2002 addresses anti-competitive agreements.

Section 4 addresses abuse of dominant position.

Sections 5 and 6 concern combinations.

Microsoft illustrates leveraging of technological control.

Google Shopping illustrates self-preferencing.

Google Android illustrates ecosystem restrictions, tying and contractual constraints.

Intel illustrates the importance of economic effects in exclusionary-rebate analysis.

Hoffman-La Roche illustrates exclusivity and the special responsibility of dominant firms.

United Brands provides foundational principles on dominance and market definition.

Airtours concerns coordinated effects and collective dominance.

Staples illustrates merger analysis.

Qualcomm illustrates competition issues in vertically related technology markets.

The key question is whether ecosystem integration creates efficiencies or is used to exclude competition.

Exam definition:
Layered digital ecosystems are interconnected digital markets or technological layers in which firms may control multiple levels of the value chain, creating potential competition concerns through self-preferencing, tying, exclusivity, data concentration, interoperability restrictions, network effects, leveraging and ecosystem lock-in.
