Who did you end up moving to? I wouldn't trust any corp that claims to be immune form court orders or interference from national agencies. No one that accepts credit card payments is really outside the reach of the Feds there. I'd rather be with a provider that doesn't try to make false claims about what they can do. If France or the UK can strong arm proton into revealing payment info, I really doubt they'd stand up any better to the USA.

If you are doing activities that might get you in trouble with a nation state please for the love of Schneier just use PGP and stop trusting ANY email provider with your messages.
