> Whatsapp does not have e2e encryption. They encrypt message traffic in transit between endpoints and their servers, but they have visibility to the data. They can and have retrieved messages for law enforcement.

Can you provide a source for that? Here [1] they state that they use e2ee. Here [2] is a tweet by Moxie Marlinspike (the founder/one of the founders of signal), that whatsapp implemented the signal protocol. Is signal also not end2end encrypted?

Signal protocol is used between whatsapp server and endpoint, not from endpoint to endpoint. Once your message is on their server, it's decrypted, archived, inspected, and then passed to its intended recipient.

This is not true.

There is a deep technical explanation about how e2ee works in WhatsApp: https://scontent-frt3-1.xx.fbcdn.net/v/t39.8562-6/271639644_...
