Many projects are doing the “not for use in California” thing. I’d set the birthday to yesterday - it is the safest. This is only useful as a do-not-track, and kids get the best protection there. For anything else - kids are well able to change their birthday on the computer, so if you want to protect kids from harmful content (whatever that is - no two people agree if you dig deep enough) you need something that is stronger than a claimed age.


There are several people who work on linux who live in California who thus are subject to California laws. There are people who don’t live in California who sometimes travel to California and thus could be subject to those laws at times (see a lawyer)
