I sense that you're arguing in good faith, but your first argument is very strange. The purpose of end-to-end encryption is that the messages cannot be read even by Apple. This is a feature that they advertise in their webpage about iMessage security. All I'm saying is that a bunch of people believe that iMessage supports end-to-end encryption and at the same time know that their messages are encrypted by a key that Apple holds and can decrypt them with via iCloud backup. That's quite literally marketing a privacy-centric product and having the reality (for the vast majority of users using the defaults) be substantially different than what was promised. To put it even more starkly, Apple advertises that they can't read your messages, and yet they can.
