Well, there _is_ E2EE in messenger, it is just off by default. I am not sure how they manage key sharing, but likely in some way that would allow them to add another device to your session relatively transparently, which means that they could always bypass it in that way. Of course, they could also bypass it by shipping a targeted software update to force your app to resubmit all the messages unencrypted.
