Apple does not have access to FaceTime keys or iMessage keys for that matter. They are truly end-to-end encrypted, and I don’t think there is any need to cheapen or muddy the term for the sake of marketers.
They can still write software to insert themselves into the key exchange flow and eavesdrop on a conversation. E.g. I don’t believe there is anything stopping Apple from pretending a participant bought a new device.
Perhaps as that was based on random internet comments. FaceTime still ends up at level 2 with Zoom and the rest because Apple can MITM the traffic without much trouble. There is no provision for the user to prevent/detect a MITM attack in FaceTime or iMessage.
So you’re saying there should be a three-level consumer standard where the third level excludes any possible consumer product? Please don’t pretend that Apple and Zoom’s approaches are equivalent here. There is a substantial difference that deserves to be acknowledged. Anyone whose threat model includes Apple subverting their own security architecture shouldn’t be using any communication platforms.
