You don't know what you don't know - or in other words, have you seen the latest research on iOS surveillance mechanisms? There could be other "undocumented" stuff that makes the encryption of Facetime Audio irrelevant.

>This product, Signal, seems to only be for iPhones. So it's even more limited.

It appears to interoperate with RedPhone, an Android app by the same authors.

In the very same doc you quote, they also say of iMessage:

"Apple does not log messages or attachments, and their contents are protected by end-to-end encryption so no one but the sender and receiver can access them. Apple cannot decrypt the data."

Which has been refuted several times.
