> iPhones intentionally don't support modern cellular messaging. There's nothing wrong with insisting they support LTE spec (RCS), like every modern smartphone does.

Clearly every modern smartphone does not support it because iPhone does not. iPhone is half of the US market. A standard that only has 50% market penetration is hardly a standard.

> Imagine if they did the same thing to, say, your telephone calls from your phone number.

I’d be happy if no one could reach me via my telephone number. There would be a lot less spam calls to ignore. I would welcome a system where no one could dial me without me granting them permission first.
