Competition Law and Ecosystem Design Strategies and Antitrust Analysis

1. Introduction

Ecosystem design strategies concern the way a business deliberately structures the relationships among its platform, customers, suppliers, developers, distributors, competitors, data systems, payment systems, and complementary products.

In competition law, ecosystem design is important because the architecture of an ecosystem can itself influence competitive conditions.

An ecosystem can be designed to:

encourage interoperability;

reduce transaction costs;

promote innovation;

create network effects;

improve security;

but it can also be designed to:

lock in users;

exclude competitors;

favour the platform's own products;

restrict interoperability;

impose exclusivity;

transfer market power into adjacent markets.

Core formula

Ecosystem Design + Market Power + Restrictive Architecture + Foreclosure = Potential Antitrust Concern

The important distinction is that integration is not itself unlawful. Competition law examines the competitive effects and legal justification of the particular design.

2. What Is an Economic or Digital Ecosystem?

An ecosystem is a network of interconnected businesses, technologies and users.

For example:

Operating System
↓
App Store
↓
Developers
↓
Applications
↓
Payments
↓
Consumers
↓
Data

A more industrial ecosystem may be:

Robot → Software → Cloud → AI → Data → Maintenance → Spare Parts

The ecosystem designer may influence the rules governing every connection.

3. Ecosystem Design vs Traditional Product Design

Traditional product design asks:

How should the product function?

Ecosystem design asks:

How should all participants interact with one another?

This may involve decisions concerning:

access;

pricing;

APIs;

interoperability;

ranking;

data sharing;

licensing;

exclusivity;

certification;

payment;

security;

developer rules.

Therefore, competition analysis must sometimes look beyond the individual product to the architecture of the overall ecosystem.

4. Major Ecosystem Design Strategies

A. Open Ecosystem

The business permits:

third-party access;

interoperability;

multiple suppliers;

independent developers;

data portability.

Competition effect

This can reduce entry barriers and encourage innovation.

But open access may also create:

cybersecurity risks;

quality-control problems;

free-riding.

Therefore, openness is not automatically required by competition law.

5. Closed Ecosystem

A closed ecosystem restricts access.

Examples:

proprietary operating system;

exclusive app distribution;

proprietary charging system;

closed industrial software;

restricted APIs.

Potential benefits

security;

quality control;

integrated user experience;

investment incentives.

Potential competition concerns

lock-in;

exclusion;

switching costs;

foreclosure;

reduced interoperability.

6. Walled-Garden Strategy

A walled garden is an ecosystem where the operator controls access to complementary products and services.

Typical structure:

Platform → Users → Developers

The platform may determine:

which applications are permitted;

how they are ranked;

how they are monetised;

which payment systems are available.

A walled garden becomes particularly important under competition law where the operator has substantial market power.

7. Interoperability-by-Design

An ecosystem can deliberately be designed to work with competing products.

Examples:

open APIs;

common standards;

data portability;

cross-platform compatibility;

interoperable payment systems.

Competition benefit

Interoperability can:

reduce switching costs;

facilitate entry;

increase consumer choice;

prevent technological lock-in.

However, mandatory interoperability may reduce incentives for investment in some circumstances. Therefore, competition analysis must consider the overall circumstances.

8. Exclusive Ecosystem Design

A company may deliberately design an ecosystem around exclusivity.

For example:

Hardware purchasers must use the manufacturer's cloud.

or:

Developers cannot distribute through competing platforms.

The competition issue is whether exclusivity prevents rivals from obtaining sufficient access to the market.

9. Bundling Strategy

An ecosystem may bundle multiple products.

Example:

Operating system + browser + cloud storage + security.

Bundling can be efficient.

But if a dominant undertaking uses its position in one market to disadvantage competitors in another, competition-law concerns may arise.

10. Tying Strategy

Tying occurs when access to one product is conditioned upon taking another product.

For example:

Industrial automation software requires the customer to use the provider's cloud.

The analysis generally considers:

market power;

separate products;

conditioning;

foreclosure;

competitive effects;

efficiencies.

11. Self-Preferencing by Design

An ecosystem designer may create ranking or recommendation rules that favour its own products.

For example:

Platform

→ Own product: Position 1

→ Rival product: Position 20

This may raise concerns where:

the platform is an important gateway;

the platform also competes downstream;

ranking materially affects customer access;

the preference disadvantages competing products.

12. Data Architecture as Competition Strategy

Data architecture can determine competitive advantage.

An ecosystem designer may decide:

who can access data;

what data can be exported;

whether developers can use data;

whether competitors can interoperate;

whether data can be combined across services.

Data lock-in

More users → More data → Better service → More users

This can create a self-reinforcing competitive advantage.

13. Switching-Cost Design

A company may design an ecosystem in ways that increase switching costs.

Examples:

proprietary data formats;

incompatible accessories;

loyalty programs;

proprietary accounts;

subscription bundles;

unavailable data portability.

Not every switching cost is unlawful.

The competition concern arises when artificial lock-in is used by a powerful undertaking to prevent effective competition.

14. Network-Effect Design

Ecosystem design can intentionally exploit network effects.

Direct network effect

More users → greater value.

Indirect network effect

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

Network effects can produce significant efficiencies.

But they can also create entry barriers and make market power durable.

15. Platform Governance

An ecosystem needs rules.

The designer may establish:

seller standards;

developer policies;

ranking rules;

pricing rules;

technical standards;

security requirements.

Competition law may examine whether these rules are:

neutral;

transparent;

discriminatory;

exclusionary;

objectively justified.

16. The "Competitor as Customer" Problem

An ecosystem designer may provide infrastructure to businesses that compete against it.

Example:

Marketplace → third-party sellers

while the marketplace also sells its own products.

Or:

Cloud provider → competing AI developers

while the cloud provider also develops its own AI models.

The platform therefore becomes:

supplier + regulator + competitor.

This can create significant competition concerns.

17. Vertical Integration

An ecosystem can combine several stages:

Manufacturing → Distribution → Software → Cloud → Payments

Vertical integration can create efficiencies.

But a dominant integrated firm may use control at one stage to disadvantage competitors at another.

This is called vertical leveraging or foreclosure.

18. Essential-Facilities Design

An ecosystem designer may control an infrastructure that competitors allegedly cannot realistically duplicate.

Examples:

dominant API;

payment infrastructure;

operating system;

telecommunications network;

industrial platform.

The essential-facilities doctrine can become relevant.

However:

A valuable facility is not automatically an essential facility.

Indispensability and the elimination of effective competition remain important considerations.

19. Algorithmic Ecosystem Design

Modern ecosystems increasingly use algorithms to control:

prices;

ranking;

recommendations;

advertising;

inventory;

access;

commissions.

The design of the algorithm can therefore affect competition.

Potential issues include:

algorithmic collusion;

discriminatory ranking;

personalised pricing;

exclusionary recommendations;

common pricing algorithms;

automated retaliation.

20. Antitrust Analysis Framework

A useful framework is:

M-P-C-E-E-R

M — Market

What relevant market or interconnected markets exist?

P — Power

Does the ecosystem operator have market power?

C — Conduct

What ecosystem design strategy is being used?

E — Exclusion

Could rivals be foreclosed?

E — Efficiencies

Are there legitimate technological or economic efficiencies?

R — Remedies

What intervention could preserve competition without destroying legitimate integration?

21. Step 1: Define the Relevant Market

Ecosystems can involve multiple markets.

For example:

smartphone operating systems;

app distribution;

mobile payments;

advertising.

A competition authority may consider:

demand substitution;

supply substitution;

multi-sided characteristics;

geographic scope;

quality;

innovation.

22. Step 2: Determine Market Power

Market power can be assessed through:

market share;

entry barriers;

network effects;

switching costs;

data;

infrastructure;

technological advantages;

customer dependence.

A large market share alone does not automatically establish unlawful conduct.

23. Step 3: Identify the Design Strategy

Ask:

Is the ecosystem open or closed?

Is access discriminatory?

Is there exclusivity?

Is there tying?

Is there self-preferencing?

Is interoperability restricted?

Is data portability limited?

24. Step 4: Assess Foreclosure

The crucial question is:

Does the ecosystem design prevent equally efficient competitors from entering or expanding?

Relevant factors include:

duration;

market coverage;

switching costs;

alternative channels;

network effects;

customer dependence;

technical barriers.

25. Step 5: Assess Innovation

Competition may be harmed through reduced innovation even when prices do not increase.

Possible effects include:

fewer technologies;

fewer developers;

reduced R&D;

slower innovation;

reduced interoperability;

elimination of potential competitors.

This is particularly important in:

AI;

robotics;

cloud;

biotechnology;

digital platforms.

26. Step 6: Examine Efficiencies

A sophisticated antitrust analysis must consider legitimate reasons for ecosystem design.

Possible efficiencies:

cybersecurity;

privacy;

product quality;

technical compatibility;

reduced costs;

faster innovation;

reduced transaction costs;

improved consumer experience.

The question is whether the restriction is necessary and proportionate to achieving those objectives.

27. UAE Competition-Law Framework

The relevant modern UAE statute is Federal Decree-Law No. 36 of 2023 on the Regulation of Competition.

For ecosystem design, the main areas of relevance include:

Restrictive agreements

Ecosystem participants cannot use cooperation as a mechanism for unlawful restriction of competition.

Abuse of dominance

A dominant ecosystem operator may face scrutiny where its design facilitates conduct such as:

discriminatory access;

unjustified refusal to deal;

tying;

restrictive technological practices;

predatory behaviour;

other exclusionary conduct.

Economic dependence

An ecosystem participant may become dependent where realistic alternatives are unavailable.

Economic concentration

Acquisitions can be relevant where an ecosystem expands through mergers, acquisitions or other concentration transactions.

28. Case Law

There is no single universal doctrine called “ecosystem design antitrust.” Courts instead apply established principles concerning dominance, tying, interoperability, refusal to deal, self-preferencing, vertical foreclosure and platform competition.

The following cases are therefore particularly useful.

Case 1: Microsoft Corp. v Commission

Case T-201/04

Microsoft's conduct concerning interoperability and tying within its software ecosystem was central to the case.

Competition principle

A dominant technological platform may face competition scrutiny where control of one technological layer is used to restrict competition in complementary markets.

Ecosystem-design relevance

Design decisions concerning:

interoperability;

software integration;

technical interfaces;

can have competitive consequences.

29. Case 2: United States v Microsoft Corp.

D.C. Circuit, 2001

The U.S. Microsoft litigation examined conduct surrounding Microsoft's Windows platform and competing technologies.

Relevance

The case demonstrates how a dominant platform can potentially use control over its core technology to influence competition in complementary products.

Ecosystem lesson

Platform architecture can become a competitive asset and, in some circumstances, a mechanism of exclusion.

30. Case 3: Bronner v Mediaprint

Case C-7/97

The case concerned access to a newspaper delivery system.

Principle

A refusal to provide access does not automatically constitute abuse of dominance.

Strict conditions concerning indispensability are important.

Ecosystem-design relevance

A company designing a closed ecosystem is not automatically required to open every proprietary component to rivals.

31. Case 4: IMS Health v NDC Health

Case C-418/01

The case concerned access to a pharmaceutical data structure.

Relevance

It addresses the difficult intersection between:

intellectual property;

interoperability;

market access;

dominance.

Ecosystem-design lesson

Proprietary architecture may legitimately be protected, but under exceptional circumstances refusal of access may raise competition concerns.

32. Case 5: Google Android

Case T-604/18; CJEU appeal C-738/22 P

The case concerned contractual restrictions in the Android ecosystem.

Issues

The case involved relationships among:

operating systems;

mobile applications;

search;

browsers;

device manufacturers.

Ecosystem-design significance

It demonstrates that competition authorities can examine the combined effect of contractual arrangements across an ecosystem.

33. Case 6: Google Shopping

Case T-612/17; CJEU appeal C-48/22 P

The case concerned Google's treatment of its own comparison-shopping service in its search ecosystem.

Key concept

Self-preferencing.

Ecosystem-design relevance

The architecture of search rankings can determine which competitors obtain customer visibility.

Therefore, ranking design can become competition-relevant where a powerful gateway is involved.

34. Case 7: MEO

Case C-525/16

The case involved discriminatory pricing by a dominant undertaking.

Principle

Different treatment is not automatically an abuse; the competitive effects of the discrimination must be assessed.

Ecosystem relevance

This applies by analogy to:

different platform fees;

different API access;

different licensing conditions;

different technical support.

35. Case 8: Eturas

Case C-74/14

The case concerned a common online booking system and possible coordination among businesses using the system.

Ecosystem relevance

The case illustrates how platform architecture can become relevant to the facilitation of coordinated conduct.

An ecosystem designer must therefore consider whether its systems facilitate:

price coordination;

information exchange;

common restrictions.

36. Case 9: United States v Topkins

N.D. Cal., 2015

The prosecution involved online sellers and alleged price coordination facilitated by pricing algorithms.

Ecosystem-design relevance

An algorithmic platform cannot automatically avoid antitrust responsibility merely because commercial decisions are made through software.

The legal question remains whether there is unlawful coordination.

37. Case 10: U.S. v Apple

The U.S. antitrust litigation involving Apple provides a modern ecosystem example involving allegations concerning interconnected platform restrictions.

Issues raised include:

interoperability;

payments;

applications;

accessories;

messaging;

platform control.

Important qualification

The allegations in litigation should not be treated as established judicial findings unless and until determined by the court.

38. Case-Law Table

39. Open vs Closed Ecosystem

Neither model is automatically lawful or unlawful.

40. Ecosystem Design Red Flags

A competition-law compliance team should investigate:

Red Flag 1

Competitors cannot interoperate without justification.

Red Flag 2

The platform gives itself preferential ranking.

Red Flag 3

Customers cannot export their data.

Red Flag 4

Participants must deal exclusively with the coordinator.

Red Flag 5

The platform uses competitors' confidential data to compete against them.

Red Flag 6

Access fees are discriminatory without objective justification.

Red Flag 7

The platform prevents competing payment systems.

Red Flag 8

The platform acquires emerging competitors systematically.

Red Flag 9

Algorithms exchange sensitive competitor information.

Red Flag 10

Technical standards are designed specifically to exclude rival technologies.

41. Compliance-by-Design

Businesses can reduce competition risk by incorporating competition principles into ecosystem architecture.

A. Interoperability-by-design

Develop reasonable interfaces.

B. Neutral access

Use objective access criteria.

C. Data separation

Prevent inappropriate use of competitor information.

D. Non-discriminatory ranking

Establish transparent ranking principles.

E. Competition review

Conduct antitrust assessment before major ecosystem changes.

F. Algorithmic governance

Audit algorithms for coordination and discriminatory effects.

G. Acquisition review

Assess potential competition before acquiring emerging technology firms.

42. Remedies

Possible competition remedies include:

Behavioural

non-discrimination;

fair access;

transparent ranking;

interoperability;

data portability;

restrictions on exclusivity.

Technical

open APIs;

technical standards;

interoperability protocols;

data-transfer tools.

Structural

business separation;

divestiture;

separation of platform and competing service.

Structural remedies are generally more intrusive and depend on the applicable legal framework and evidence.

43. Advanced Antitrust Model

For an ecosystem design problem, use:

D-P-A-F-E-R

D — Design
How is the ecosystem architected?

P — Power
Does the designer possess market power?

A — Access
Who controls access to the ecosystem?

F — Foreclosure
Are competing businesses disadvantaged?

E — Efficiencies
What legitimate benefits justify the design?

R — Remedies
What intervention would preserve competition?

44. Exam-Oriented Answer

Ecosystem design strategies and antitrust analysis concern the relationship between the architecture of an integrated business ecosystem and competition. Ecosystem design may determine access, interoperability, data use, ranking, payment, exclusivity, pricing and participation rules.

An open ecosystem may encourage competition and innovation, whereas a closed ecosystem can increase control, switching costs and network effects. Where the ecosystem operator has substantial market power, practices such as self-preferencing, tying, bundling, exclusivity, discriminatory access, refusal to deal, data leveraging, interoperability restrictions and algorithmic coordination may raise competition concerns.

Under the UAE competition framework, these issues can intersect with rules governing restrictive agreements, abuse of dominance, economic dependence and economic concentrations. Cases such as Microsoft, Bronner, IMS Health, Google Android, Google Shopping and MEO provide important comparative principles.

The fundamental analytical question is:

Does the ecosystem's design primarily create legitimate efficiencies and innovation, or does it use market power to restrict effective competition?

45. Final Revision Sheet

Six essential cases

Microsoft — T-201/04

Bronner — C-7/97

IMS Health — C-418/01

Google Android — T-604/18

Google Shopping — T-612/17
