Vast majority of Proton users signed up because Proton promises your data is safe at rest. Even from them. In fact, they specifically advertise this protects them from subpoenas because they cannot provide decrypted copy of user’s data.
Of course, the only emails that are encrypted with proton are proton->proton. Mail between proton and anyone else, like say gmail, isn’t encrypted unless you pgp it separately.
Not fully correct. Mails between Proton users are E2E encrypted where Proton cannot see them, and rest of the emails are encrypted at rest once Proton receives them. Based on the audits and open source code, Proton is not keeping a copy of those emails when it receives them, and once they are encrypted, nobody but you will have access to it

Guess the question is if your private key is actually only yours or do they have some copy they can use somewhere.
