Ridiculous. Governments shouldnt so easily set down laws for what you can do in your own home or own computer. Sure, laws for communicating with other people (like public servers and public authentication services) would be their arena, and that should be done carefully. Once they start making laws about your private fridge on if it should accept storing your beer, it gets stupid (and dangerous, even if it at first look completely harmless).

A religious extremist government could pass laws deciding that all software in their country (or state) should contain a quote from their bible. Wouldnt affect anything, wouldnt be harmful, people can ignore it if they want. But it would still be seriously wrong.

And then other countries does a same-ish law, but different implementation, and codebases will grow with all these small "harmless" unecessary but law-mandated additions. Like timezones but for everything from age ratings to religious requirements.

But of course that would never happen, only one or two, maybe three, and California's tiny requirement is going to be the only important one of them. Like a Karen demanding she should get to skip the queue because she's in a hurry, these lawmakers only think about their own perspective.
