End-to-end encryption works only because WhatsApp (or iMessage or whichever other service) servers store everyone's public keys: https://stratechery.com/2018/open-closed-and-privacy/ https://stratechery.com/2018/open-closed-and-privacy/
Open, secure, usable by ordinary people: choose two.
Insecure, open, usable: Google Chat
Secure, centralised, usable: WhatsApp
Secure, open, poor UX: PGP.
If you're building a consumer-grade service, rather than a niche service usable only by security geeks, and you're arguing for end-to-end encryption, then you're knowingly or unknowingly arguing for centralisation and against interoperability.
