It's also what Linux should be doing in general,. It's not even the US. It's a fucking state in the US that is doing something stupid on behalf of Meta.

Any Linux distro should just put the onus on the CA legislature. Have a TOS that specifies that it does not comply with CA law, and as such isn't legal there. No need for any implementation change. Businesses in CA can take it upon themselves to comply by maintaining a fork that adds any sort of BS. But, more than likely, the dimwits who didn't know better and listened to Meta, might be surprised to find jusy how much everything runs on Linux (except a tiny number of user facing devices).
