I honestly see no advantage of Proton Mail over just saying “let’s take this conversation to a secure platform (e.g. Signal).” And if you do that, you’re using a protocol that was actually •designed• for E2E encryption instead of trying to bolt it on the side.
I am not a Proton customer, so I may be missing something here. Am I?
If I do understand correctly, it seems like the security benefit of Proton Mail is mostly theoretical, weak sauce in practice.
