I agree that opening up an RCS API would be great but I don’t think that’s what the original comment was getting at
And even if there was an API that 3rd party apps could hook into, I don’t think that would skew the numbers in any meaningful way.
With something as important as messaging, average consumers (at least in the US) are just going to stick with whichever chat app comes on their phone. They aren’t going to reach out and search for anything else. That’s how we got to this point in the first place and why iMessage is so ubiquitous
