I've read about that case, and as far as I know Protonmail did exactly as they said in their Terms: they have to follow the law of their country. Being an activist, it's dumb and unneeded to let your email provider know your IP address. There's a reason Protonmail is available on protonmailrmez3lotccipshtkleegetolb73fuirgj7r4o4vfu7ozyd.onion.

What other option than complying with national laws do they have? They're not above the law on their country. All they can do is choose a jurisdiction that matches the level of privacy they want to offer as closely as possible.
