A coalition of more than 100 technology companies, advocacy organizations, and developers has issued a pointed open letter to Google, warning that the Android operating system—long celebrated as the world’s most widely deployed open-source mobile platform—is being systematically locked down in ways that threaten competition, innovation, and user freedom. The letter, published on the website KeepAndroidOpen.org, represents one of the most organized industry pushbacks against Google’s stewardship of Android in the platform’s 17-year history.
The signatories include prominent names from across the technology spectrum: the Electronic Frontier Foundation, the Mozilla Foundation, Epic Games, Spotify, Match Group, the Computer & Communications Industry Association, and dozens of smaller app developers and digital rights groups. Their collective argument is straightforward but far-reaching: Google is using a combination of technical restrictions, contractual obligations, and policy changes to erode the openness that made Android dominant in the first place, and regulators around the world should take notice.
The Core Grievances: Sideloading, Default Apps, and the Play Store’s Iron Gate
At the heart of the dispute is a series of changes Google has made—or plans to make—to how Android handles app installation from sources outside the Google Play Store, a practice commonly known as sideloading. According to the open letter, Google has progressively introduced friction into the sideloading process, including enhanced warning screens, repeated confirmation dialogs, and restrictions on certain app permissions for sideloaded applications. The coalition argues these measures go well beyond reasonable security precautions and are designed to steer users away from alternative distribution channels.
The letter specifically calls out Google’s Play Integrity API, a tool that allows app developers to check whether an app was installed through the Play Store and whether the device meets certain security criteria. While Google frames this as an anti-fraud and security measure, critics say it gives developers a Google-endorsed mechanism to block sideloaded versions of their apps entirely. The result, the coalition contends, is a system where even developers who want to distribute outside the Play Store find themselves unable to offer a fully functional product.
A Platform Built on Openness, Now Accused of Closing Its Doors
Android was launched in 2008 with an explicit promise of openness. The Android Open Source Project (AOSP) allowed any manufacturer to build devices using the operating system, and any developer to distribute software without going through a single gatekeeper. That openness was a key differentiator from Apple’s iOS, which has always maintained strict control over app distribution through its App Store. Over the years, Android’s open architecture enabled a sprawling hardware market, with Samsung, Xiaomi, OnePlus, and hundreds of other manufacturers building devices for every price point and market segment.
But as the KeepAndroidOpen.org coalition argues, the gap between Android’s theoretical openness and its practical reality has been widening for years. Google’s Mobile Application Distribution Agreement (MADA), which manufacturers must sign to include Google Play Services and core Google apps, effectively requires device makers to pre-install a bundle of Google applications and set Google as the default search engine. While manufacturers are technically free to ship Android without these agreements, doing so means forgoing access to the Play Store and the vast library of apps that depend on Google Play Services—a trade-off few companies are willing to make.
Legal and Regulatory Pressure Mounting on Multiple Fronts
The open letter arrives at a moment when Google is facing intensifying legal scrutiny over its mobile business practices. In October 2024, a U.S. federal judge ruled that Google had maintained an illegal monopoly in the search market, a case that prominently featured the company’s payments to device manufacturers and browser makers to secure default search placement. The remedies phase of that case is ongoing, and the Department of Justice has signaled that structural changes to Google’s mobile distribution agreements could be on the table.
In the European Union, the Digital Markets Act (DMA) has designated Google as a gatekeeper for several of its services, including the Play Store and the Android operating system itself. Under the DMA, Google is required to allow sideloading, permit alternative app stores, and refrain from unfairly favoring its own services. Google has made some adjustments in response—including allowing alternative billing systems within apps distributed through the Play Store—but critics say these changes have been grudging and insufficient. The European Commission opened a formal investigation in 2024 into whether Google’s compliance measures meet the law’s requirements.
What the Coalition Is Demanding
The demands laid out in the open letter are specific and technical. The coalition wants Google to stop adding unnecessary friction to sideloading, to ensure that sideloaded apps have access to the same device capabilities and APIs as Play Store-distributed apps, and to prohibit the use of the Play Integrity API to discriminate against apps based on their installation source. The signatories also call on Google to decouple core Android functionality from proprietary Google Play Services, arguing that too many basic features—push notifications, location services, in-app payments—are tied to Google’s proprietary layer rather than the open-source base.
Additionally, the coalition is asking Google to reform its agreements with device manufacturers. The letter argues that MADA and related contracts should not require bundling of Google apps or default settings, and that manufacturers should be free to ship devices with alternative app stores, search engines, and digital assistants without losing access to the Play Store. The group frames these demands not as an attack on Google’s business model, but as a restoration of the competitive conditions that Android’s open-source license was supposed to guarantee.
Google’s Defense: Security, Quality, and User Trust
Google has consistently defended its approach by pointing to security concerns. The company argues that sideloading is a primary vector for malware on Android devices and that the Play Store’s review process, while imperfect, provides a meaningful layer of protection for users. Google Play Protect, the company’s built-in malware scanner, flags millions of potentially harmful apps each year, and Google has published data showing that devices which install apps exclusively from the Play Store have significantly lower malware infection rates.
On the question of manufacturer agreements, Google has argued that bundling requirements ensure a consistent, high-quality user experience across the fragmented Android device market. Without baseline requirements, the company says, users could end up with devices that lack access to essential services, leading to confusion and dissatisfaction that would ultimately reflect poorly on the Android brand. Google has also noted that manufacturers are free to pre-install competing apps alongside Google’s offerings—a point the coalition disputes in practice, given the contractual limitations on home screen placement and default settings.
The Broader Stakes for Mobile Competition
The fight over Android’s openness carries implications that extend well beyond the mobile phone market. Android runs on tablets, smartwatches, televisions, automobiles, and an expanding array of connected devices. If Google succeeds in tightening control over how software is distributed and installed on these platforms, the effects will ripple through industries from entertainment to automotive to healthcare. Conversely, if regulators or courts force Google to loosen its grip, the resulting competitive dynamics could reshape how billions of people interact with technology.
The coalition’s effort also reflects a growing tension in the technology industry between platform operators and the developers and companies that build on those platforms. Similar disputes have played out with Apple’s App Store policies, Amazon’s treatment of third-party sellers, and Microsoft’s management of the Windows platform. In each case, the platform operator argues that centralized control benefits users through security and quality assurance, while competitors and developers argue that such control stifles innovation and extracts monopoly rents.
An Industry at a Crossroads
For now, the KeepAndroidOpen coalition is pressing its case on multiple fronts: through public advocacy, regulatory engagement, and support for ongoing litigation. The group’s website includes detailed technical analyses of the specific changes Google has made to Android’s sideloading process, as well as economic arguments about the costs of Google’s distribution practices to consumers and competitors. Several signatories, including Epic Games and Spotify, have been vocal critics of both Google and Apple’s app store policies for years and have pursued their own legal challenges.
The outcome of this dispute will likely be shaped as much by regulators and judges as by market forces. With antitrust cases proceeding in the United States, the European Union, India, South Korea, and Japan, Google faces a global patchwork of legal challenges to its mobile business practices. The company’s responses to these pressures—whether through voluntary concessions, court-ordered remedies, or regulatory compliance—will determine whether Android remains a meaningfully open platform or becomes, as the coalition warns, an open-source project in name only.
The stakes are high on both sides. Google’s mobile advertising and Play Store commission revenues depend on maintaining a central role in the Android experience. But the companies and organizations behind KeepAndroidOpen argue that the long-term health of the mobile market depends on preserving the competitive openness that made Android successful in the first place. As one passage from the open letter puts it, the question is whether Android’s openness will remain “a reality or merely a relic.”
