because Boeing or why?

Google Messages app already falls back to SMS automatically if RCS fails. SMS is not going anywhere.

yes I know Apple isn’t a Telecoms company but you need a SIM from a Telecoms company to use iMessage. RCS runs over the Internet too, yet you also need a SIM card for that. Also Telecoms companies aren’t designing message protocols anymore. I don’t think you know what you’re talking about.

what do you mean Telecoms companies aren’t allowed to add E2EE? there is no such regulation I’m aware of.

besides, how would Apple have been supporting E2EE in iMessage for so long if Telecoms companies weren’t allowed?

could be a motivation issue, but not a regulation issue.
