Messaging and email are different applications. People use messaging apps because of the rise of the mobile devices, not because these messaging apps use forward secrecy or ECC. Don’t try to link that adoption to crypto protocols!

Also, very few of these users actually use secure versions such as signal or wire. They all happily post on Facebook‘s messenger and WhatsApp and don’t care about crypto.

Messaging applications use protocols derived from Signal Protocol rather than PGP because they had the opportunity to do something better than PGP. The first secure messengers did use PGP; designing a new messenger based on PGP would be malpractice.

WhatsApp uses Signal Protocol, and protects many order of magnitude more messages every day --- or, if you like, bytes of plaintext --- than PGP ever has or will.

Email not being a messaging protocol is... a take.
