I try to limit my Proton use to only their VPN, and after their comments I'm trying to decide between switching to AirVPN or doing my own VPN since I need portforwarding for torrenting. I switched from ProtonMail to Mailbox.org a while ago to not keep my eggs in one basket.
I think everyone highlighting the police is correct but also cherrypicking (for lack of a better statement). Like Tuta isn't gonna go to jail for you either lol. All companies have to cooperate with the government in some form. I do agree that Proton should stop advertising like it won't or that it's failproof though. If they really cared, they would make guides on how to use their services in a way that gives little to no information to the police if demanded. And emphasizing that the email isn't encrypted if the other user isn't a ProtonMail account or using PGP.
