That's a fair point that I hadn't considered. I agree that's a negative, but for me, personally, I don't consider it a showstopper. I do get that other people might, though, and am understanding of that position.

On the flip side, most people using RCS would otherwise be using an @gmail.com address as their identity if that was how it worked. I'd say that's probably better than the carrier owning the identity, but it's still not ideal.
