Linux age verification exemption

Archived — this story has rotated out of today’s deck. It is kept here in full.

The gist

California lawmakers unanimously passed AB 1856, exempting Linux from age-verification law.
The exemption spares open-source OSes from compliance, but SteamOS remains uncertain.

Background

California's Digital Age Assurance Act (DAAA) would require operating systems to verify users' ages and send age signals. Linux developers and the Electronic Frontier Foundation criticized the law, arguing it would burden open-source projects. In response, Assemblymember Buffy Wicks introduced an amendment exempting software distributed under open-source licenses like GPL, MIT, BSD, and Apache. The amendment passed unanimously and now awaits the governor's signature.
