Doesn’t RCS support E2EE if properly implemented? I seem to recall reading that the spec for RCS supports this, but it’s just that carriers won’t enable it.
Google has implemented their own E2EE on top of RCS (based on Signal’s messaging for one to one conversations, based on MLS for group chats), but they haven’t published any specifications for that.
Ahh, this must be what I was thinking of, then. Thanks for clarifying!
It’s also handing control over messaging back to carriers
I don’t really see any issue in this, as RCS was meant as an upgrade of the SMS protocol. Moreover, as the smartphone market is now pretty much a duopoly between Google and Apple, and pretty much what is not Apple is Google, it was natural for Google to also come up with an alternative to iMessage of theirs. Because that’s what it is currently. I’m surprised Apple accepted to implement RCS after all because of this tbh.
Imo, both Google, Apple could have worked with the major carriers to implement a solution like this over GSM (and not requiring you to use mobile data). For me, that’s the advantage of the SMS over any IM app out there (including Matrix, XMPP etc.): you’re not required to turn on your data in order to use it. It’s just right there. For the current implementations of RCS/iMessage respectively, I don’t see any advantage over just using WhatsApp or Facebook Messenger for example.
