Can you please point to me where it states Googles “version” of RCS can’t also interface with telecom based RCS?
Because it seems from my reading the Google just has some enhanced features on top of RCS (like e2e encryption) when both sides are through Google, but that doesn’t mean it doesn’t work with telecoms as well, unlike Apples walled garden of iMessage which doesn’t work with anything else lol.
And…? I don’t get your point, that’s what I’m arguing, Apple specifically made iMessage unable to interact with anything else intentionally, they very well could have figured out a way to bring it to other platforms but specifically chose not to.
