Linux manages to avoid the age verification apocalypse, but SteamOS isn’t in the clear yet
California’s Digital Age Assurance Act, set to take effect January 1, 2027, would require operating systems to implement age verification checks and restrict access to certain functions. The regulation prompted significant concern among Linux developers worried about compliance burden on open-source projects. However, Assembly Bill 1856, an amendment to the legislation, recently passed with a unanimous 39-0 vote, providing crucial relief by exempting open-source operating systems from verification requirements.
The exemption specifically targets certain types of operating system distributions—the amendment’s language precludes “a person or entity that distributes” in ways that would create compliance obligations. This represents a major victory for the Linux community and open-source advocates, preventing implementation and liability burdens for community-driven projects. The exemption acknowledges the distinct challenges faced by non-proprietary systems compared to commercially controlled platforms.
Despite the relief for open-source Linux, SteamOS remains in an uncertain position. While based on Linux, SteamOS may not qualify for the exemption depending on how its distribution and Valve’s role are legally classified. This ambiguity means Steam Deck’s OS could potentially face the original verification requirements, setting it apart from traditional open-source operating systems.
