California’s age verification crusade just hit an unexpected speed bump: lawmakers discovered that open source exists. AB 1856, a proposed amendment to the state’s Digital Age Assurance Act, would exempt operating systems distributed under licenses allowing copying, redistribution, and modification. Translation: your Ubuntu install won’t interrogate you about your birthday, but Windows absolutely will.
The original law, AB 1043, requires operating systems to collect users’ ages at setup and signal age brackets to apps starting January 2027.
Violations carry penalties up to $7,500 per affected child.
The mandate treats your OS as the central age gatekeeper—a concept that works fine for Microsoft’s walled garden but breaks spectacularly when applied to volunteer-run Linux distributions.
Open source communities reacted like you’d expect when bureaucrats demand they become age police.
MidnightBSD developers threatened to ban California users entirely rather than implement compliance systems they can’t afford.
The Electronic Frontier Foundation warned that such laws entrench major platforms while crushing smaller projects that lack legal teams and centralized infrastructure.
AB 1856’s carve-out reads like someone finally explained open source licensing to legislators.
The exemption covers any software with rights to “copy, redistribute, and modify“—perfectly describing GPL, BSD, and MIT licenses that power mainstream Linux distributions.
Meanwhile, proprietary ecosystems like Windows, macOS, and mobile platforms remain firmly in the compliance crosshairs.
Your choice of operating system now determines whether California treats you like a potential child safety risk.
Boot Windows or macOS, and prepare for birthday verification theater that critics argue protects nobody while expanding surveillance infrastructure.
SteamOS occupies murky middle ground—open source Linux with a proprietary store bolted on.
This regulatory split reflects a broader truth: governments can mandate identity checkpoints on corporate platforms but struggle to police truly decentralized systems. As 25+ states rush to implement similar age laws, with Colorado already drafting open source exemptions, we’re witnessing the emergence of a two-tier internet. One track demands papers at every digital border crossing. The other preserves the wild west ethos that built the web—if you know where to find it.
