> RCS isn't an open platform in practice. It isn't even as open as SMS/MMS. It heavily depends on proprietary Google and carrier infrastructure in practice. We can start by replicating Google's approach and then we can work on only using carrier services for carriers where it's actually supported.
What is the point of RCS though? It seems to be strictly inferior to Signal. It seems a Google product meant to serve Google. I wouldn't hate it if GrapheneOS would totally ignore RCS. I fail to see any value in it, but maybe I am lacking information(?)
RCS was DOA from day one as far as I'm concerned. The carriers being involved in any capacity deeper than providing dumb pipes alone was enough to make it pointless, but no E2E in the base spec makes it extra pointless. They may as well have just extended SMS to be more capable, because that's what they've effectively created.
The point of the exercise is for Google and Apple to maintain control over the ecosystem.
RCS is technically superior (protocol, transport, security, all of it) but is captured from the start on the technical level by design by the big players. From the perspective of the vast majority of users who have very limited technical awareness, it was silently slipped in as an upgrade at one point or another. This means that those not adopting the proprietary BigTech solution are perceived as being difficult by insisting on using software that's now perceived as outdated or as otherwise mildly incompatible.
From [0], it seems that RCS can use the cellular signal instead of LTE or 5G:

Except... what carriers still remain using their own RCS carrier services and haven't been pressured by Google to adopt Jive?
I don't really get why so many Americans want RCS to succeed though. Do you guys not remember when carriers charged 10p/text? Why on earth would you want to give any power at all back to those people?
After getting several family group chats finally converted over to RCS, one day my phone just started absolutely refusing to verify my connection to the RCS servers. Instead of any kind of notification, I was just silently not sending or receiving messages for nearly an entire day. I had to disable RCS on my phone, which created a several day long issue where some chats would just fall back to SMS and others absolutely refused to work, or strange interactions with Apple devices where certain messages would not be displayed. After enough trouble with it I convinced everyone to switch to a third party messaging app. I'll never turn RCS on again, I can't trust that it won't just start silently failing.
Text messages in iMessage or SMS are a fairly US-centric relic.
That's not to say overseas is better - Europe depends on Whatsapp - but outside the US the whole 'blue box' thing isn't even a thing.
