Age verification is no longer just a debate about social networks, adult websites or mobile app stores. In the United States, the issue has moved closer to the core of the device itself: the operating system. Several state-level bills and laws aim to make operating systems and app stores collect age information during account or device setup and make that signal available to app developers.
The stated goal is to protect minors online. The concern from the Linux and open-source community is different: a requirement designed around closed ecosystems such as iOS, Android, Windows or macOS could become technically awkward, legally risky and philosophically incompatible with open systems that were never built to collect that kind of user data.
The clearest recent example is Colorado’s SB26-051, an age attestation bill introduced in January 2026. The proposal was designed to make operating systems collect users’ ages and provide that information to app developers so they could disable age-inappropriate experiences for children. But its initial wording alarmed open-source developers because it risked sweeping Linux distributions into a compliance model built for commercial platforms with centralised accounts and app stores.
Why Linux does not fit neatly into this model
Linux is not a single operating system controlled by one company. It is a family of distributions built by companies, foundations, volunteer communities, universities, independent maintainers and small teams. Some distributions are sold preinstalled on hardware, while others are downloaded as ISOs, copied to USB drives, modified, forked and redistributed without any central authority.
That matters because many age-verification proposals assume there is an “operating system provider” capable of controlling setup, collecting an age or date of birth, storing an age signal and exposing that information to applications through an API. That may be feasible for Apple, Google or Microsoft. It is far less straightforward for a small Linux vendor, a volunteer distribution or a project maintained outside the United States.
Carl Richell, founder and CEO of System76, became one of the most visible voices in this debate. System76 develops Pop!_OS, a Linux distribution used by developers, students and desktop Linux users. Richell warned that Colorado’s bill, in its original form, could have applied to his company and imposed a compliance burden that smaller open-source projects could not realistically absorb. He also argued that mandatory age-gating could undermine one of Linux’s core strengths: allowing anyone, including young people, to learn how computers work by studying, modifying and building with open-source software.
System76 has made the same point in its own public statement. The company argues that if age-attestation systems become the standard, apps and websites may assume the lowest age bracket when a signal is missing. In practice, that could leave Linux users with a degraded internet experience unless their distribution implements an age signal system.
Colorado created an open-source carveout
Richell spent weeks working with Colorado lawmakers and appeared before a Colorado House committee on April 23, 2026, to argue that open-source operating systems should not be treated like closed commercial platforms. According to The Verge, his advocacy succeeded: on May 1, SB26-051 passed with an exemption for open-source operating systems such as Linux. Richell described the exemption as a possible template for other legislatures.
The final carveout is important because it is tied to open-source user rights: the ability to copy, redistribute and modify software without platform-imposed technical or contractual restrictions on installing modified versions. In other words, Colorado’s amended bill tries to distinguish genuinely open systems from closed platforms that merely expose some source code or developer tools.
The Colorado episode is a partial victory for Linux, but it does not end the debate. Other states have adopted or are considering similar rules, and not all of them include the same explicit open-source exemption.
California’s AB 1043, the Digital Age Assurance Act, is already law. Governor Gavin Newsom signed it in October 2025, and its main requirements are due to take effect on January 1, 2027. The law requires device operating systems and app stores to ask users for their age or date of birth during the setup of a new phone or computer. For devices set up before that date, OS providers such as Apple or Google must provide a way for users to enter their ages by July 1, 2027.
California’s approach does not require users to upload government IDs or obtain parental consent for every app download, which makes it less invasive than some other age-verification models. But it still places the age signal at the operating system and app store layer. That is exactly what worries open-source developers, because the law was not written around the decentralised reality of Linux.
Privacy, forks and legal uncertainty
The Linux community’s objection is not simply political. It is also practical.
First, there is the privacy issue. Many Linux distributions collect little or no personal data. Some do not require an online account at all. Adding an age field, a local or cloud-backed API and a mechanism to pass that information to apps would create a new category of user data that many projects have deliberately avoided collecting.
Second, open-source software can be modified. If a distribution added an age-verification component, another developer could fork the project and remove it. A user could also disable or replace it locally. This is not a loophole; it is part of how free and open-source software works. That makes enforcement difficult and raises an uncomfortable question for regulators: who is liable when a user modifies the system?
Third, many open-source projects do not have legal departments, compliance teams or large budgets. A big technology company can implement age-signalling APIs, negotiate with regulators and absorb legal risk. A small distribution maintained by volunteers cannot do that at the same scale. The Verge reported that some projects are considering whether to wait, comply minimally, add disclaimers or avoid certain jurisdictions altogether.
The Linux Foundation has also criticised this kind of mandate. Michael Dolan, senior vice president of strategic programs at the foundation, told The Verge that open-source age verification mandates create new privacy risks while remaining easy to bypass, calling them “security theater” rather than improved child safety.
This does not mean the open-source community dismisses child safety. The disagreement is over where responsibility should sit and whether operating-system-level age signalling is the right mechanism. System76’s position is that education, trust and better digital literacy are more effective than pushing age checks into systems that were not designed to collect identity-related data.
A regulation wave that could make Linux more attractive
The paradox is that these laws could make Linux more appealing to privacy-conscious users. If mainstream operating systems become more closely tied to age signals, identity layers and app-level restrictions, some users may look for alternatives that preserve local control and data minimisation.
But Linux cannot simply ignore the regulatory trend. Commercial Linux vendors that sell hardware or services in the United States will need to monitor each state-level law, assess whether they qualify as providers, and decide how to respond. Community distributions may face less direct exposure, especially if they are based outside the US, but legal uncertainty alone can still create pressure.
The broader lesson for lawmakers is clear: regulating the internet through the operating system is not the same as regulating an app store. Closed ecosystems and open systems operate differently. A law that seems technically simple when applied to iOS or Android can become messy when applied to Linux, BSD, SteamOS, container platforms, repositories or community-built software.
Colorado’s open-source exemption offers one possible path. It acknowledges that software which users can freely copy, modify and redistribute should not be treated like a locked-down commercial platform. Whether California, New York, Illinois or other states follow that approach remains an open question.
The fight over age verification is becoming one of the defining battles of the regulated internet. It is no longer only about whether a website should ask for a date of birth. It is about whether computers should be designed to carry an age signal from the operating system upward, ready for apps and services to query.
For Linux, that touches a central principle: the user should control the machine, not the platform.
Frequently asked questions
What do these age-verification laws require?
They generally require operating systems or app stores to collect an age or date of birth during setup and provide an age signal to app developers so they can adapt or restrict access to content.
Why are Linux developers concerned?
Because Linux is decentralised, often privacy-focused and usually does not rely on a single account system or controlled app store. Adding age signalling could create technical, legal and privacy problems.
Did Colorado exempt Linux?
Yes. Colorado’s SB26-051 passed with an exemption for open-source operating systems after advocacy from System76 CEO Carl Richell and others in the open-source community.
Does California’s law apply to Linux?
California’s AB 1043 applies to operating system providers and app stores, but how it will be enforced against decentralised open-source Linux distributions remains unclear. The law is scheduled to take effect on January 1, 2027.
