RCS is a terrible messaging standard because it is dependent on a carrier phone bill. It's anti-internet and should not be promoted or advocated for. My Verizon bill is not my identity. Apple lock-in is bad, and the solution is carrier lock-in? Nah.

RCS is carrier lock-in because it makes a carrier number your identity, which is tied to a bill. Other services make email the basis of your identity. Email is free. They don't take your identity if you stop paying a bill. Email identity works from non-phone devices.
Imagine you can't afford a phone or can only afford intermittent phone service. Phone identity locks you out of a service. With email identity, you can go to a library and sign up for the service. You can use it on a friend's device. You can use it at a public internet kiosk.
