Cooperation isn't quite the same as cooperation. There's a world of difference between sharing intelligence on other countries and working together when conducting espionage elsewhere, vs actively attacking domestic targets. Rule of law is taken seriously, and government hacking is a thing - but the scope is very very narrow.

If Protonmail servers are hacked, it's game over (that could be mitigated by having verified client code, but at this time there's the web client that is served dynamically, and the mobile clients are closed source...). That is where Protonmail are at a huge disadvantage unless they have a really really good security team. Server hacking is done a dime a dozen nowadays.
