TL;DR
Linux developers are actively resisting new age verification laws in several US states, including Colorado and California, arguing these laws threaten open-source principles and user privacy. Some are working with lawmakers to modify legislation, while others are taking more direct action.
Linux developers and open-source advocates are actively opposing recent legislative efforts to impose age verification requirements on operating systems, including Colorado’s SB26-051 and California’s AB 1043. These laws aim to enforce age-gating on digital platforms but are seen by many in the open-source community as incompatible with their principles and practical realities.
In January, Colorado introduced SB26-051, proposing that operating systems collect users’ ages and pass this data to app developers, primarily targeting commercial platforms like iOS and Android. Denver-based System76 founder Carl Richell recognized that this law could also impact open-source Linux distributions, which lack the resources to implement such age-gating measures easily. Richell publicly opposed the bill, working with lawmakers to secure an exemption for open-source systems, which was granted on May 1st.
Meanwhile, California passed AB 1043, requiring operating systems and app stores to collect users’ ages during device setup starting January 2027. This legislation raised concerns among open-source developers about how to comply without compromising privacy or creating security vulnerabilities. Some, like Canonical and Fedora, are reviewing their options, while others, such as MidnightBSD, have taken a more adversarial stance, announcing plans to restrict Californians from using their software for desktop purposes from 2027.
The core issue revolves around the difficulty of implementing reliable age verification in open-source projects, which are often volunteer-driven and prioritize user privacy and minimal data collection. Experts like Michael Dolan of the Linux Foundation have criticized these laws as ‘security theater’ that do little to enhance child safety but increase privacy risks and technical challenges for open-source developers.
Why It Matters
This resistance highlights a fundamental conflict between legislative efforts to regulate online safety and the open-source ethos of privacy, transparency, and user control. As more states consider similar laws, open-source communities face the dilemma of complying without betraying core principles or risking legal repercussions. The outcome could influence how future laws are crafted and how open-source projects adapt to legal requirements.

Background
Legislation like Colorado’s SB26-051 and California’s AB 1043 reflect growing efforts nationwide to enforce age verification on digital platforms, driven by concerns over online safety for minors. These laws come amid broader debates about privacy, data security, and the role of government regulation in digital spaces. Historically, open-source projects have prioritized user privacy and minimal data collection, making compliance with such laws particularly challenging.
“Everyone should have access to the ability to create with a computer. Open-source software makes that possible. It ensures that everyone, regardless of age or background, can learn, experiment, and build at the most fundamental level.”
— Carl Richell, CEO of System76
“This is security theater, not improved child safety. Age verification mandates on open source systems create new privacy risks while remaining easily circumvented.”
— Michael Dolan, SVP of strategic programs at the Linux Foundation
“A local API or an added ‘age’ field might be the simplest workaround, but there are no concrete plans yet.”
— Jef Spaleta, Fedora Project leader

What Remains Unclear
It remains unclear how many open-source projects will implement technical solutions, oppose laws outright, or seek legal exemptions. The long-term legal and technical implications of these laws for open-source communities are still developing, with some developers actively exploring options and others resisting outright.

What’s Next
Legislators are expected to review and refine these laws in response to open-source community feedback. Developers will continue to debate compliance strategies, and legal challenges or legislative amendments may arise. Monitoring how different projects respond will be key to understanding the future landscape of open-source software and law.

Key Questions
How will open-source projects comply with age verification laws?
Some are considering technical solutions like local APIs or adding age fields, while others are resisting or seeking exemptions. The approach varies depending on resources and principles.
Can open-source software be exempt from these laws?
In Colorado, exemptions were granted for open-source systems like Linux. However, legal interpretations and future legislation remain uncertain.
What are the privacy concerns related to age verification?
Implementing age verification can require collecting personal data, increasing privacy risks and potential security vulnerabilities, especially in open-source projects that prioritize minimal data collection.
Will these laws affect everyday users of Linux and open-source software?
Potentially, yes. If projects choose to comply, users may face restrictions or altered functionalities. Some projects may restrict access or modify their licensing to resist compliance.
