You don’t need that: Proton will only surrender accounts/information to local authorities with the appropriate paperwork - and that’s their selling point on privacy, swiss law being pretty protective of privacy ; in this case, a corpus of evidence has been submitted by a recognized foreign entity & considered valid for action in regard to swiss law.

That’s what makes proton secure for journalists, political opponents and such: no swiss judge will enable any random dictator to get a dissident’s info, it won’t fly with swiss law. And if that escalates to bogus criminal charges, it is still up to a swiss judge to decide how and if to proceed.

You put your trust in Switzerland here, not in a nerdy business with an atom-smashing background.
