It's unfortunate that RCS is basically a de-facto Google walled garden in most countries. On android you can only use RCS in the Google Messages app and trying to build your own is explicitly blocked. [1] And of course the bonus that rooted devices are banned from RCS. All the propaganda Google spread to get Apple onboard (only with Google's blessing of course, Google could kick apple off if they wanted) was such a big win for them.
As a business I wanted RCS to be a simple upgrade to SMS, but instead they came up with this mess. Businesses using RCS for Business can send messages to anyone, but customers wanting to get in touch with your business can't. They can only reply to a message you sent first. And of course Google is the gatekeeper for anyone to be allowed to use it.
