I mean, that’s just capitalism. They aren’t mandating what other states do. They’re only regulating what companies do in their own state. Companies are more than free to just not sell their products in California and then aren’t bound by the regulations in California. But capitalism being capitalism, companies will choose to meet the regulations, because California is one of the largest economies in the world and they stand to make a lot more money by doing business there. And since it’s generally cheaper to make all their products the same instead of specializing a portion of their products for California only, products in other states end up conforming to the regulations incidentally.

The Texas law, on the other hand, is attempting to impose its legislation on other states and the people in them, instead of on companies that are doing business within their borders. The California regulations does not impact the laws and regulations of another state. It does impact how companies behave in other states, but only because they really really want to do business in California and it’s just easier to make all of their products conform to the standard instead of making California-only products just for them. I would maybe compare it with the way that media companies would conform to Chinese censorship in their movies, games, etc, because the Chinese market is absolutely huge and they stood to make an absolute killing by conforming. Companies will always choose to make as much money as they can, and that’s just capitalism. The Texas law is an entirely different beast and it’s probably constitutionally unenforceable for the most part.
