Honestly, at this point I don't think there is hope for RCS.

And even if there was: I really don't like the idea of an (at least somewhat) carrier-controlled messaging service. Especially the lack of multi-device messaging/not being able to access my account without my phone is really frustrating.

We had all of that with instant messengers in the early 2000s (proprietary or open/federated) – RCS seems like a big step back in that regard.
