RCS is a really nice thing in principle, because SMS/MMS infrastructure is just awfully outdated from security standpoint.
Though, replacing SMS/MMS infrastructure which is internetless yet cross-carrier by making it a internet-first and tied to a single meta-carrier under the hood kind of defeats the purpose overall. There was an attempt to build an independent carrier-deployable implementation of RCS, yet it turned out to be bought off by Google :(
Neither am I. It’s just sad…
