You may need to explain further.
All BSDs have developers all over the place, and mirrors all over, including in the EU.
Both NetBSD & OpenBSD have cute (and probably outdated) little world maps showing where their developers live.
All of them are supported by foundations that collect money & hardware for their devs.
I suspect that if the current US government was to bar access to BSD repos and mirrors, a lot of the foundations would move at least partially to better places.
