The only RCS implementation that has E2EE is Google Messages (well, pretty much the only one available, but anyways), RCS as a protocol doesn’t have it by default, right?
Well, that’s kind of concerning for iMessage users. Will they completely lose SMS and MMS support? What about when the iMessage or RCS servers are unreachable?
It’s pretty confusing, but I don’t think so. Read the last bit: “when available”. SMS and MMS will be available, but RCS will take priority over them when available.
Does this mean they may not actually roll this feature out, or may yank it if they win their appeal?
That’s the Signal Protocol. RCS is Google’s attempt to replace SMS/MMS
