California lawmakers have passed a bill exempting open-source operating systems, such as Linux, from the state's Digital Age Assurance Act, which requires age verification for device users. The exemption applies to software distributed under licenses like GPL, MIT, BSD, and Apache. This move comes after criticism from Linux developers and the Electronic Frontier Foundation. The law is set to take effect on January 1, 2027, and will still apply to operating systems like Windows, macOS, iOS, and Android.
