California legislators are moving to exempt open-source operating systems from a state age-verification law. Assembly Member Buffy Wicks introduced Amendment 1856 on February 11, 2026. The latest version of the amendment dates back to May 18, 2026. This legislative action targets the Digital Age Assurance Act.
Assembly Bill 1856 proposes exemption for open-source operating systems
The proposed amendment specifically defines an operating system provider as an entity that does not distribute software under licenses allowing users to copy, redistribute, and modify it. Mainstream Linux distributions like Debian, Fedora, Ubuntu, Arch Linux, and Mint would likely fall under this exemption. The original law required OS-level age verification starting January 1, 2027.

Commercial platforms with proprietary app ecosystems may remain subject to the requirements. Reports suggest that SteamOS could still face regulation due to its ties to a proprietary storefront. Valve's gaming platform ships with the closed Steam client and store, potentially placing it closer to Apple or Google from a regulatory standpoint.
The amendment aims to protect open-source software from mandatory age checks at the operating system level. This legislative shift follows significant backlash against the original Digital Age Assurance Act requirements. The proposal highlights the ongoing tension between privacy regulations and open software distribution models.
