You’re absolutely right, but the knuckle-draggers are too busy with their FOMO to hear it.

iMessage supports a dense layer of features in excess of what’s possible with the RCS standard. RCS is a decent fallback, and maybe progress could be made towards supporting it as a fallback. But the issue is that not even all Android phones enable RCS by default, meaning iMessage would have to have a fallback and a second fallback.

And honestly, the bottom line is that Apple is unlikely to prioritize implementing RCS until their customer base is asking them to do so, which they largely aren’t. The vast majority of the anger towards Apple regarding RCS is from people who don’t buy Apple phones, or from Apple’s direct competitors seeking to improve their products. Apple users (myself included) don’t really care because a marginally better SMS experience is still going to be worse than iMessage, and if I’m really looking for rich cross-platform messaging, I can use any of the dozen widely-used apps that do exactly that.
