@0x1C3B00DA @Gargron @natanji Domains are frequently seized. Check out recent news regarding Backpage or Sci-Hub. Sci-Hub's actually a great example because they've been trying to evade the judgment by jumping to different country code domains.
The Microsoft data question involved data about a US user, that just happened to be stored in Ireland. Cloud providers can't evade the law by holding data in other countries.
But if a given entity both lives in, and operates using services in, a country where their activity is legal, there should be nothing that the US can do about it.
I was a bit surprised Cloudflare pulled Switter so easily/quickly, they've put up much more of a fight against these things before, but expecting a US company not to obey US law was a mistake, Switter should never have gone with them.
