TL;DR
- Users who have rooted their phone, have their bootloader unlocked or are using some custom ROMs report that their RCS messages are not being sent, even though RCS shows them as connected.
- The Google Messages app does not show any error messages when blocking RCS messages of these users and does not send the messages out as SMS or MMS either.
- Google famously campaigned for Apple to include RCS messaging in iMessage but is now blocking it for certain Android users.
Wait… It sucks cause they are actively working to break it. Not because its flawed. Its no different than apples stupid bubbles.
I think the point is that if it can be sabotaged by a central authority, it sucks. Both Apple and Google suck.
