There are a lot of messaging apps, but most of them don't interoperate with each other. So if you want to use the same app for communicating with everyone, you either need to somehow convince everyone to install your app of choice, (and in the case of iMessage buy the same kind of phone) or use SMS/MMS. And by not supporting RCS, Apple is effectively crippling that between iPhones and Android.
