Besides the fact that Proton is based in Switzerland where government warrants aren’t issued willy-nilly, please learn how the mathematics behind encryption works – or, if not, at least trust that it does. For emails that are sent E2EE, Proton can only have garbled data that requires a key they don’t have.

Email is not end to end encrypted and this is the first of protons many misleading claims. Best case the contents is encrypted but not info like recipents address or sender’s IP. Leading to less knowledgeable activists not understanding that using protons vpn and their email together can actually lead to users giving proton more then enough info for law enforcement to track someo e down.

Proton doesnt even hide this if you look at their reports they comply with court orders regularly. In theory proton could also back door any of their users keys since everything is done on the fly in the browser and proton controls all of the code. This is something their predecessors had been ordered to do and chose to shutdown instead of complying. Somehow i dont see proton opting to close up shop just to protect a few users who theyre told are criminals.

People who actually care about encryption already had a solution long before proton, called PGP and thats yet to be broken. Why other then vendor lock in would you encourage people to use anything else? (this is a criticism i have of tuta also)

Also just fyi proton moved out of Switzerland last year for guess what… Legal reasons!

Glad to hear you agree with me and dont want to debate because literally none of what ive said is speculative.
