As others have said, subsidiary companies. Perfectly normal, and SpaceX is certainly big enough to do so... if they're willing. I mean, the whole "move fast and break things" approach may lead to viewing regulations (especially other countries' regulations) as things you just ignore until they prove that you can't.

And, let's say that I'm a wanna-be SpaceX user in Namibia. I drive over the border to, say, Botswana. I buy a receiver. I drive back into Namibia. I may be illegal, but is SpaceX breaking the law? Even if they are, what can Namibia do to SpaceX about it? They can't do much, precisely because SpaceX has no business presence in Namibia.
