I have mixed feelings on this one. It absolutely sucks for Ukrainians, of course. But OFAC and similar sanctions specify an embargo on Russian-occupied areas of Ukraine. If any system, subprocessor, or service can't make the region distinction, and can only identify Ukraine as a whole, and you can't replace it easily, you find yourself in a tough spot of blocking all of Ukraine or needing to shutdown all US operations.
@smeg @pluralistic I'm not arguing whether the legal implementation of the sanctions is correct.
I want just to point out that sanctions which hurt the vulnerable people as much (if not more) as the aggressors are actively harmful.
