@1ll173r47 @protonmail @ProtonCalendar @protonvpn @Fairphone @FediFollows I don't know what the numbers are, but if we were to survey, we'd have to divide the stats into 2 catorgies: expert-to-novice and novice-to-novice (probably safe to assume expert-to-expert comms excludes webmail). The novice-to-novice case is probably a disaster on par with gmail-to-gmail no crypto, or at best proton_web-to-proton_web.
