At some point, words become meaningless platitudes that are simply invalidated by the next big ToS update. Facebook have a major incentive in being able to read our messages, so I fully expect them to march in the direction of figuring out how to sell the the walkback of e2e in the future. It'll be dressed up as for our "safety" or so that their "partners" can add some sort of "value", but it will come.
also the issue of device-backups containing the unecrypted message history which is beeing shared from google to facebook.
For your second point, how would Google ever get my device backup? I guess if you are using Android and worried about your privacy, what you should switch is not your messenger app, but your OS.
second point; you and i may not be using android and google backup, a vast majority does.
