They are using the same language as Apple talking about iMessage and FaceTime. Apple talks about end to end encryption, but one end is iCloud which is why you can get your messages simultaneously on all devices.

There is a big difference there though. In transit, iMessage and FaceTime backups are end-to-end encrypted, it's just the iMessage backups on iCloud that also store the key.
FaceTime chats, though, truly are end-to-end encrypted and the calls aren't backed up like iMessages are.

Thank you for providing some clarity on the issue. Apple did not when I read their page here: https://support.apple.com/en-us/HT209110
They merely mention that backups to iCloud happen automatically by default, and not that doing so means the default is that Apple can view and decrypt all your messages.

And, backup is optional.
That's not true at all. iMessage is really end-to-end encrypted.
Two options impact it: "Messages in iCloud" re-encrypts and uploads messages to the user's iCloud account and stores the key in iCloud Keychain (also end-to-end encrypted).
Only when enabling iCloud backup will that key be revealed to Apple.

It's entirely possible to do multi-device end-to-end encryption. See Signal or XMPP+OMEMO.
Isn't that just for text? I know Signal uses WebRTC for Audio & Video and doesn't yet support group chats, (unless something changed recently)?

Yeah, the parent conversation was about whether iMessage is end-to-end encrypted. GP claimed that it cannot be due to it supporting multi-device sync, which is not true.
