The FreeBSD Foundatioin is based in Boulder, Colorado, USA.

OpenBSD is based in Calgary, Alberta, Canada.

NetBSD is a non-profit based out of Deleware, USA

I am not sure exactly what you mean by "US-focused" though. I do not think the US government has much direct influence in practice. Both governance and engineering contributions in BSD are highly distributed internationally.

That said, FreeBSD in particular has quite a lot of corporate contribution. Netflix is a heavy user of and contributor to FreeBSD for example. And the recent $750,000 laptop push in FreeBSD is being driven by Quantum Leap Research out of Virginia.

The fact that the BSD systems have less coporate reliance does not necessarily offer more protection though. There is less corporate "control" simply because the BSD systems are less important economically.

You could fork Linux anytime you like and your fork would than have as little corporate control as NetBSD. And just like NetBSD, not taking US corporate contributions would mean less engineering investmetn overall and potentially having to do more yourself.

I mean, it would probably be easier for the EU or China to fork Linux than it would be for them to migrate to OpenBSD if they wanted independence from US exposure.
