While Google is a major pusher of RCS, the standard is owned by GSMA. The entire standard is also published and freely available. Furthermore, RCS messages are not required to use Google’s Jibe platform; other companies are free to use their own. For example, many EU carriers do not use Jibe servers. Not all RCS messages go through Google servers. Technically the standard is even open enough to use individually, but you will realistically run into road blocks setting it up yourself. In any case, please stop regurgitating this nonsense.
The whole iMessage/RCS conversation is really only relevant in the US; in other countries basically everyone uses WhatsApp or Kakao or LINE or whatever the local favorite is. In the US, there is no industry-standard RCS. It’s theoretically a carrier-based messaging service but all of the carriers outsourced it to Google so, as an alternative to iMessage, the option is a proprietary extension of RCS running on Google servers, something that is exactly as open as iMessage itself.
If you want a true industry standard way to send messages to people, the iPhone has had that since 2007: email.
RCS is not an open standard, it’s just Google’s version of iMessage and it all goes through their servers. Stop regurgitating Google propaganda

Is there any open source SMS app that supports RCS right now?
