California lawmakers propose exemption for Linux distributions from age-verification mandates
The proposed amendment redefines the term “operating system provider” to exclude software permitting modification and redistribution, potentially sparing major Linux distros from compliance requirements scheduled for 2027.
California lawmakers have introduced a legislative amendment aimed at exempting open-source operating systems, including most Linux distributions, from the state’s stringent age-verification requirements. Assembly Member Buffy Wicks, who authored the original legislation, proposed Assembly Bill 1856 to modify the Digital Age Assurance Act, a move that follows significant opposition from developers and privacy advocates regarding the scope of the initial law.
The proposed amendment, dated May 18, 2026, seeks to redefine the term “operating system provider” to explicitly exclude software distributed under licenses that permit users to copy, redistribute, and modify the code. This legislative adjustment is expected to shield mainstream Linux distributions such as Debian, Fedora, Ubuntu, Arch Linux, and Mint from the compliance mandates that are scheduled to take effect on January 1, 2027.
The original Digital Age Assurance Act, passed in late 2025, required operating systems to collect user age data during device setup and expose an “age bracket signal” to applications. Critics, including the Electronic Frontier Foundation, argued that the law was invasive and technically unworkable for decentralized, community-run projects that lack the centralised control structures found in commercial platforms like Apple’s iOS or Google’s Android.
While the amendment narrows the scope of the law, it does not repeal the Digital Age Assurance Act entirely. Consequently, proprietary platforms may remain subject to the regulations. Valve’s SteamOS, for instance, could still fall under the law’s purview because it ships with the proprietary Steam storefront and client, potentially classifying it closer to commercial app ecosystems than to open-source software.
Assembly Bill 1856 was initially introduced by Wicks on February 11, 2026, with the open-source exemption language appearing in later revisions. As of May 19, 2026, the bill had been read a second time and ordered to a third reading in the California legislature, with committee reviews expected to follow in June.
