👍CA Law Exempts Open-Source OSes From Digital Age Assurance Act
Linux and SteamOS users can breathe easy
TL;DR
California's AB 1856 exempts open-source OSes from collecting user age data, a win for Linux and SteamOS users. The law takes effect January 1, 2027, but leaves SteamOS's status unclear.
California's legislature has passed Assembly Bill 1856, exempting open-source operating systems from the State's Digital Age Assurance Act. This change ends a year of uncertainty for Linux distributions and SteamOS, which were previously unsure if they'd need to collect user age data during account setup. The law's amendments redefine 'operating system provider' to exclude entities distributing software under licenses like GPL, MIT, BSD, and Apache. The law's definition of an application excludes software components not offered as standalone executables through app stores. Windows, macOS, iOS, and Android remain in scope, requiring age collection from January 1, 2027. GrapheneOS, distributed under open-source MIT and Apache licenses, is now fully exempt.
