Device Manufacturer Restrictions and Competition Effects

1. Introduction

Device manufacturer restrictions are contractual, technical, commercial, or ecosystem-level measures imposed by manufacturers of smartphones, tablets, computers, smart TVs, wearables, connected vehicles, IoT devices, and similar hardware. These restrictions can govern which applications may be installed, which payment systems may be used, which accessories are compatible, which operating systems or software services can operate, how developers obtain access to hardware functions, and whether users can switch to competing products or services.

Such restrictions are not automatically anti-competitive. A manufacturer may legitimately impose restrictions for security, privacy, interoperability, quality control, safety, intellectual-property protection, or technical reliability. Competition concerns arise where restrictions are used by a firm with substantial market power to exclude rivals, foreclose distribution channels, raise competitors' costs, prevent interoperability, create switching costs, or extend dominance from one market into an adjacent market.

2. Main Forms of Device Manufacturer Restrictions

A. Pre-installation restrictions

A manufacturer may require a device to ship with particular applications or services pre-installed while making competing applications harder to access.

Examples include:

• mandatory search or browser installation;
• default-assistant arrangements;
• compulsory application bundles;
• restrictions on removing manufacturer applications;
• preferential placement on the home screen.

The competition issue is whether the arrangement gives the manufacturer's services an artificial distribution advantage.

B. Default-setting restrictions

Manufacturers can determine:

• default search engine;
• default browser;
• default payment application;
• default map service;
• default digital assistant;
• default app store.

Defaults matter because many consumers do not change them. Consequently, a contractual default can function as a significant distribution bottleneck.

C. Application-store restrictions

A device manufacturer may require developers to distribute applications through its own application store.

Restrictions may concern:

• alternative app stores;
• direct application downloads;
• sideloading;
• alternative payment systems;
• external purchasing links;
• commission arrangements;
• app-store approval.

These restrictions can become particularly significant where the manufacturer controls both the device operating system and application distribution.

D. Payment-system restrictions

Manufacturers may prevent applications from using competing payment systems or require developers to use the manufacturer's payment infrastructure.

Potential effects include:

1. increased transaction costs;
2. commissions paid by developers;
3. reduced competition between payment providers;
4. higher prices or reduced innovation;
5. reduced ability of developers to establish direct customer relationships.

E. Hardware-access restrictions

Manufacturers can restrict third parties' access to:

• NFC;
• Bluetooth;
• cameras;
• biometric authentication;
• location data;
• secure elements;
• APIs;
• vehicle interfaces;
• health sensors;
• charging protocols.

Where access to a technically essential or commercially important function is denied selectively, competition authorities may examine whether the restriction constitutes exclusionary conduct or discriminatory access.

F. Accessory and interoperability restrictions

Manufacturers may design ecosystems in which competing accessories work less effectively.

Examples include:

• proprietary connectors;
• authentication chips;
• software certification;
• restricted APIs;
• compatibility limitations;
• licensing requirements;
• technical degradation of third-party accessories.

The competition question is whether such restrictions represent legitimate technical design or are being used to foreclose competing accessory manufacturers.

3. Competition-Law Theories Potentially Engaged

A. Abuse of dominance

Where a device manufacturer has a dominant position, restrictions may be examined under abuse-of-dominance provisions.

The basic analytical sequence is:

Market definition → market power → restrictive conduct → foreclosure → effects → objective justification → proportionality

The important point is that being a successful device manufacturer is not itself unlawful. Competition law generally targets exclusionary conduct rather than dominance as such.

B. Tying and bundling

A manufacturer may possess power in a device or operating-system market and use that power to promote another product.

For example:

Dominant mobile operating system → mandatory search service → restricted competing search services.

Authorities may ask whether:

1. two separate products exist;
2. the undertaking has power over the tying product;
3. customers are effectively compelled to obtain the tied product;
4. the arrangement forecloses competitors;
5. there is an objective justification.

C. Exclusive dealing

A manufacturer may require distributors, carriers, developers, or retailers to use only its ecosystem.

Exclusive arrangements can restrict rival manufacturers or service providers from obtaining sufficient distribution.

The relevant issue is generally foreclosure, not merely the existence of exclusivity.

D. Refusal to supply or provide interoperability

A manufacturer controlling a critical platform may refuse competitors access to an interface or technical capability.

This raises difficult questions because competition law must balance:

• competition;
• innovation;
• property rights;
• security;
• technical design autonomy.

A refusal is therefore not automatically unlawful.

E. Discriminatory access

A manufacturer may provide its own applications or affiliated businesses with access that independent competitors cannot obtain.

Potential examples include:

• superior APIs;
• privileged device data;
• earlier technical access;
• better system integration;
• preferential app-store treatment.

This can create vertical leverage from hardware into software or services.

4. Important Case Laws

1. United States v. Microsoft Corp. (D.C. Circuit, 2001)

Facts

Microsoft possessed substantial power in the market for Intel-compatible PC operating systems. The litigation concerned Microsoft's conduct toward competing browsers, particularly Netscape.

Microsoft engaged in contractual and technical practices designed to protect the position of Internet Explorer and restrict distribution opportunities for competing browsers.

Legal significance

The case established an important principle for technology markets:

A dominant platform can violate competition law when contractual or technical restrictions are used to exclude competing technologies.

The court distinguished between legitimate product integration and conduct whose purpose or effect was to suppress competition.

Relevance to device manufacturers

A device manufacturer controlling an operating system could similarly face scrutiny where it:

• restricts competing applications;
• prevents alternative distribution;
• uses technical restrictions to disadvantage rivals;
• ties complementary services to the platform.

The case is particularly important because technical architecture itself can have competitive consequences.

5. European Commission — Google Android (2018)

Facts

The European Commission examined Google's conduct concerning the Android mobile operating system.

The Commission found concerns involving:

• tying Google Search and Chrome to the Google Play Store;
• anti-fragmentation arrangements;
• payments to certain manufacturers and mobile-network operators for exclusive pre-installation of Google Search.

Legal significance

The case demonstrated how control over a mobile operating-system ecosystem can provide leverage into adjacent markets.

The Commission's analysis focused on the interaction between:

Android → Google Play → Search → browser → mobile distribution

Competition effects

Restrictions surrounding pre-installation and distribution could:

• reduce opportunities for rival search providers;
• reinforce network effects;
• make market entry more difficult;
• influence consumer defaults;
• strengthen ecosystem dependency.

Device-manufacturer lesson

Contracts between an operating-system provider and device manufacturers can themselves become important competition-law instruments.

6. Google Shopping (European Commission, 2017; General Court, 2021)

Facts

Google was found to have systematically favoured its comparison-shopping service in its general search results while demoting competing comparison-shopping services.

Although this was not principally a device-manufacturer case, it is highly relevant to platform self-preferencing.

Legal significance

The case illustrates how control over an important access point can be used to favour an affiliated service.

Relevance to device manufacturers

A device manufacturer controlling:

• the operating system;
• search interface;
• app store;
• voice assistant;
• browser;
• recommendation system

could potentially create similar concerns if its platform systematically favours its own services over competing services.

The underlying competition issue is leveraging control over an important interface into an adjacent market.

7. Apple — App Store / Epic Games Litigation

Epic Games, Inc. v. Apple Inc. (U.S. District Court, 2021; Ninth Circuit proceedings)

Facts

Epic challenged Apple's restrictions concerning distribution of applications and payment mechanisms on iOS.

Among the issues were Apple's:

• control over application distribution;
• restrictions concerning alternative payment mechanisms;
• App Store rules;
• commission structure.

Legal significance

The case demonstrates the complexity of determining whether control over an integrated device ecosystem constitutes unlawful monopolization or legitimate platform governance.

The court did not accept all of Epic's antitrust theories, while finding under California law that Apple's anti-steering restrictions violated the state's unfair-competition law.

Competition relevance

The litigation highlights several important issues:

• app-store access;
• alternative payment systems;
• developer commissions;
• steering restrictions;
• ecosystem control;
• switching costs;
• consumer choice.

It also demonstrates why technical and contractual restrictions must be assessed individually rather than automatically treated as antitrust violations.
