In a move that could reshape the iOS ecosystem, a proposed U.S. bill aims to compel Apple to open its tightly controlled App Store to third-party app stores and sideloading. This legislative push, driven by bipartisan support, seeks to dismantle what critics call Apple’s monopolistic grip on app distribution and in-app payments. As debates over competition, security, and consumer choice intensify, this development could have far-reaching implications for iPhone users, developers, and the tech industry at large. Let’s dive into the details of this bill, its potential impact, and why it’s sparking such heated discussion.
The Open App Markets Act: Breaking Apple’s Walled Garden
Introduced in August 2021, the Open App Markets Act is a bipartisan effort led by Senators Marsha Blackburn (R-TN), Richard Blumenthal (D-CT), and Amy Klobuchar (D-MN). The legislation targets companies like Apple and Google, which operate app stores with over 50 million U.S. users. If passed, the bill would require Apple to allow third-party app stores on iOS devices and permit sideloading—installing apps directly from sources outside the App Store. Additionally, it would prohibit Apple from mandating its in-app payment system, which currently imposes a 15% to 30% commission on developers.
The bill’s proponents argue that Apple’s restrictive policies stifle competition and innovation. By controlling app distribution and payments, Apple allegedly limits developers’ ability to offer competitive pricing and reach consumers directly. Companies like Spotify and Epic Games, which have long criticized Apple’s practices, back the legislation, claiming it would level the playing field and foster a more open digital economy.
However, the bill includes provisions allowing Apple to argue that its restrictions are necessary for user privacy, security, or legal compliance. This clause acknowledges Apple’s long-standing defense that its closed ecosystem protects users from malware and fraud.
Why Apple Resists Third-Party App Stores
Apple has consistently opposed efforts to open its platform, arguing that third-party app stores and sideloading would compromise iOS security. CEO Tim Cook has likened such changes to turning the App Store into a “flea market,” suggesting that unregulated app sources could erode user trust and reduce app downloads. Apple’s senior vice president, Craig Federighi, has called sideloading a “cyber criminal’s best friend,” warning of increased malware risks.
The company points to its rigorous App Store review process, which it claims ensures apps meet high standards for privacy and security. Apple also highlights its Small Business Program, which reduces commissions to 15% for developers earning less than $1 million annually, as evidence of its efforts to support smaller creators. Yet, developers like Epic Games argue that these measures don’t go far enough, and Apple’s 30% commission on larger developers remains a point of contention.
Apple’s resistance isn’t just about security—it’s also about revenue. The App Store generates an estimated $20 billion annually, with profit margins exceeding 75%. Allowing third-party app stores could erode this income by enabling developers to bypass Apple’s payment system.
The Broader Context: Global Pressure on Apple
The U.S. bill is part of a global wave of regulatory scrutiny. In the European Union, the Digital Markets Act (DMA), set to take effect in 2024, will force Apple to allow third-party app stores and sideloading on iOS devices. Apple has already begun preparing for these changes, with reports indicating that iOS 17 will include support for alternative app marketplaces in the EU.
Elsewhere, countries like South Korea and the Netherlands have mandated that Apple allow alternative payment systems, though Apple continues to charge commissions on these transactions. In the U.S., the Epic Games v. Apple lawsuit resulted in a 2021 ruling requiring Apple to permit developers to link to external payment options, though Apple has appealed this decision to the Supreme Court.
These global efforts reflect growing frustration with Apple’s control over the iOS ecosystem. Critics argue that Apple’s policies not only harm developers but also limit consumer choice by preventing access to apps and payment methods outside the App Store.
What This Means for iOS Users
For iPhone and iPad users, the proposed bill could usher in significant changes. Third-party app stores might offer apps unavailable on the App Store, such as Fortnite, which was removed after Epic Games violated Apple’s payment rules. Users could also benefit from lower prices if developers pass on savings from avoiding Apple’s commissions.
However, these benefits come with risks. Third-party app stores may not enforce the same privacy and security standards as Apple, potentially exposing users to malware or data breaches. Kaspersky’s cybersecurity experts warn that iOS could see an uptick in malware if alternative marketplaces aren’t rigorously vetted. Apple’s notarization process, which scans apps for security threats, may mitigate some risks, but it’s less stringent than the App Store’s manual review.
Parental controls could also be affected. While screen-time limits would still apply, restrictions on in-app purchases or app approvals might not function consistently with third-party apps, raising concerns for families.
The Developer Perspective: Opportunity or Chaos?
For developers, the bill promises greater freedom. They could distribute apps through their own stores, use alternative payment systems, and communicate directly with users about pricing options. This could reduce costs and allow smaller developers to compete with tech giants.
Yet, some developers worry about fragmentation. Without a single, trusted App Store, users might hesitate to download from less reputable sources, reducing app visibility. Additionally, managing multiple app stores could increase development and distribution costs, particularly for smaller teams.
Epic Games CEO Tim Sweeney has hailed recent court rulings against Apple as a “significant win” for developers, emphasizing the need for competition in payment services. However, Apple’s critics, including Spotify, argue that the company’s “malicious compliance” with regulations—such as imposing complex rules for third-party stores—could undermine the bill’s intent.
The Road Ahead: Will the Bill Pass?
While the Open App Markets Act has bipartisan support, its path to becoming law is uncertain. A 2022 report suggested that similar legislation faced challenges in gaining full Senate approval, and Apple’s lobbying efforts have historically thwarted state-level bills in places like Arizona and North Dakota.
Recent developments, however, indicate mounting pressure. A May 2025 court ruling found Apple in violation of a previous order to reform its App Store practices, referring the company to federal prosecutors for contempt. This ruling, coupled with the EU’s DMA, suggests that Apple’s ability to resist change may be waning.
If the bill passes, it could set a precedent for other platforms. Critics have questioned why similar rules aren’t applied to gaming consoles like Xbox, PlayStation, or Nintendo Switch, which also impose strict app distribution and payment policies. This inconsistency could fuel further debate about fairness across the tech industry.
