People required to comply

I know for a fact (having been subject to them) that Russian sanctions work exactly the same way as USA sanctions do. The only difference between the two of note is the relative economic power of the two countries - I would be annoyed if I could never visit the USA again or be paid by a company that does business in the USA as well as my local country, but it doesn't hugely bother me that I'd have problems visiting Russia or being paid by a Russian business.

And that ends up being the core problem with where you locate an open-source foundation; international politics means that unless the world is at peace, you're really choosing the place whose sanctions decisions are least impactful on you, not a place from where you can ignore sanctions.
