California lawmakers pass Linux exemption from upcoming age-verification law

Assembly Bill 1856 exempts open-source operating systems from state age-data collection mandates set to take effect in 2027.

The short version

  • California lawmakers unanimously passed Assembly Bill 1856, which exempts open-source operating systems distributed under permissive and copyleft licenses like GPL, MIT, BSD, and Apache from state age-verification requirements.
  • Proprietary operating systems such as Windows, macOS, iOS, and Android must still collect user age data during device account setup beginning January 1, 2027.
  • The legislation now heads to Governor Gavin Newsom, who signed the original Digital Age Assurance Act last year.

  • Proprietary operating systems remain subject to the Digital Age Assurance Act and must begin collecting user age data during account setup on January 1, 2027.[Hacker News]
  • The amendments create exemptions for software components distributed through package managers and browser extension stores, while adding a safe harbor provision protecting platforms from liability over inaccurate age signals.[Hacker News]
