AB-1856 is currently undergoing committee reviews and could be voted on by the California State Legislature in June. AB-1856 makes some important adjustments to exempt most Linux distributions from being affected by California's age verification law.
One of the important pieces of AB 1856 is amending their age verification law with:
"(2) “Operating system provider” does not mean a person or entity that distributes an operating system or application under license terms that permit a recipient to copy, redistribute, and modify the software."
And on the application side:
"(2) “Application” does not include software components that are not themselves offered to consumers as a stand-alone executable application through a covered application store."
While this does clear the vast majority of open-source Linux distributions from being impacted by this law in California, it would still impact platforms like Valve's SteamOS. With Steam shipping the proprietary Steam client it would still be treated as a covered application store and likely still affected by California's original law along with any other similar Linux distribution with proprietary apps.
At least AB-1856 if passed in California will hopefully clear up the situation for the vast majority of the Linux distributions and other open-source operating systems out there.
