Never said I trusted Proton, Fastmail, governments, lawyers, or coders. I queried whether open source code partly mitigates the questions raised by the OP. There’s a weird political undercurrent to your response that doesn’t quite match my comment.

There is some degree of trust involved in almost all online activities. Unless you’re personally in charge of this particular forum, you’re also trusting a specific authority. And even if you are the owner, you’re still relying on a number of protocols whose code I doubt you’ve personally audited.
