For some reason I have it in the back of my mind that they were at one point accused of being a honeypot for US intelligence because of their association with MIT. Probably complete BS, but maybe not. Are they as open source as they claim to be? Looks like they’re on github. F-Droid seems to think they have some Google libraries or whatever that they use.
ProtonMail users, how do you like/dislike it?
Proton AG lost me as a customer the minute they backdoored a binding arbitration clause into their TOS last year.
The difficulty of proving damages in breach of privacy cases combined with generally weak privacy legislation globally means the threat of a class action often serves as one of the only practical deterrents to abuses of power by corporations controlling sensitive personal information. By changing its terms of service, Proton essentially immunized itself from suffering any significant penalty in the event its negligence leads to a mass breach of privacy of its users.
Tactics like the use of binding arbitration clauses are hallmarks of inherently untrustworthy corporations.
