It’s absolutely worth requesting your data to be deleted regardless of where you live by claiming to live in California…
I do think it’s possible that some of them won’t delete your data upon request, failing to comply with the law
That’s not failure to comply with the law if you don’t actually live in California.
People have a legal location of residence in the US.
If you want to establish legal residency in a state, you’re typically looking at doing something like spending the majority of the year there.
EDIT: I’d also be pretty confident, though the article doesn’t talk about it, that California won’t normally have jurisdiction for California state law unless a data broker is doing business in California, and that that will also be a constraining factor. Like, if a data broker company is only doing business in, say, Russia, the US will not enforce rulings against them regarding California state law in general.
