Proton doesn’t have E2EE, they decrypt and then encrypt your emails. So if they do it with email, why not to repeat same thing in standard notes?Also they develop proprietary software(docs for example) and if you are interested in all proton’s problems watch mental outlaw’s video about it.
Proton will buy it, so proton will read all your notes (we remember proton’s “E2EE”)
