The open-source community is mobilizing against a wave of state laws that would require operating systems to collect and share users' ages. These laws, modeled after California's AB 1043, aim to age-gate the internet by embedding verification into the core of device software. While proponents argue they protect children from harmful content, Linux developers warn they threaten the fundamental principles of open-source computing: privacy, customization, and user freedom.

Colorado's SB26-051: A Near Miss for Linux

In January 2026, Colorado lawmakers introduced SB26-051, a bill requiring operating systems to collect age data during setup and pass it to app developers. The bill was clearly designed for commercial platforms like iOS and Android, but it would have swept Linux into its scope. Carl Richell, founder and CEO of System76 (the company behind Pop!_OS), saw the threat immediately. “The law would likely apply to my own small business,” Richell told The Verge. “Without the resources of a company like Apple and Google, complying would be a major logistical headache. More broadly, it betrays the principles of open source and limits its potential.”

Richell began working with state lawmakers, spending weeks pushing for changes and sharing updates online. On April 23rd, he testified before a Colorado House committee, arguing that open-source software is “the best way to learn computing” and that age-gating would block children from root access and customization. His persistence paid off: the final bill, passed on May 1st, includes an exemption for open-source operating systems that permit copying, redistribution, and modification without platform restrictions. “We have created a template that I hope other legislatures adopt,” Richell said.

The Broader Challenge for Open Source

Richell’s success is isolated. Similar bills are advancing in Illinois (HB4140) and New York (S8102A), and California’s AB 1043 takes effect January 1, 2027. The laws pose practical problems for volunteer-run projects: implementing age verification requires resources, and the decentralized nature of open source makes enforcement nearly impossible. If a developer adds age-gating code, anyone can fork the project and strip it out, raising questions of liability.

“Protecting children online is absolutely important,” said Michael Dolan, SVP of strategic programs at the Linux Foundation. “However, age verification mandates imposed on open source systems create new privacy risks while remaining easily circumvented. This is security theater, not improved child safety.”

Diverse Responses: Caution, Defiance, and Innovation

Leading distributions are still figuring out their approach. Canonical, the company behind Ubuntu, stated it is “reviewing the legislation internally with legal counsel, but there are currently no concrete plans.” Fedora Project leader Jef Spaleta suggested a “local API” or an age field in the user database. Other developers are more confrontational.

MidnightBSD modified its license to explicitly exclude California residents from using its desktop OS after January 1, 2027. Though technically unenforceable, the move aims to avoid liability without changing the software. Garuda Linux, based in Europe, argued the law doesn’t apply because its servers are in Finland and Germany. Artyom Zorin of Zorin OS, based in Ireland, echoed that California law “does not (yet) apply where I live.”

One project, Ageless Linux, takes outright defiance a step further. Created by developer John McCardle, it is a script for Debian that replaces the age field with a stub API returning no data. McCardle’s site declares, “The question is not whether this is legal. The question is whether anyone wants to spend the State of California’s money suing a person who handed a child a Linux USB drive.” He even outlines plans for a sub-$15 single-board computer running Ageless Linux, complete with an ageless app store.

Privacy vs. Child Safety: The Core Conflict

Many privacy advocates oppose age verification laws outright. They argue that centralized, easily bypassed measures create new attack surfaces and fail to protect children. “Open source exemptions reflect a better understanding of how these operating systems are developed and distributed, but they do not address the fundamental problem,” said the Linux Foundation’s Dolan. “There are more effective and less invasive ways to protect children online.”

Richell agrees, but pragmatically sees carveouts as a necessary compromise. “SB51 is about identifying who’s a kid in a closed ecosystem,” he said. “Applying that broadly can push age verification into open systems that were never built to collect that kind of information in the first place.” The Colorado exemption is tied to “user rights inherent in open source software,” avoiding coverage of projects that “don’t align with the spirit of open source.”

Zorin OS’s CEO warned that invasive measures will backfire: “The more invasive the age verification measures, the more likely users are to circumvent them. In the worst-case scenario, Linux users could simply remove or overwrite the age verification components. It is up to lawmakers to make the effort to understand this reality.”

The battle is far from over. With California’s deadline approaching and more states considering similar bills, Linux developers face a critical choice: engage with legislators, risk noncompliance, or redesign their systems in ways that betray their core values. The outcome could reshape not only the Linux ecosystem but the entire internet’s approach to age verification.
