A comment on End-to-End Encryption and Messaging Interoperability.

RCS and its support in the Android Messages app is conspicuously absent from mention. I wonder if there are any RCS supporting open source messaging apps that don't require giving your message contents to Google. Or is RCM somehow closed off from third party apps?

Edit: seems that according to https://www.netmanias.com/en/post/techdocs/8154/lte-rcs/gsma... it's entangled to IMS which is to my understanding walled off from normal apps. You can't, I think, make VoLTE calls through your carriers IMS SIP infra with Android SIP apps or SIP implementing dialer apps from app store etc. I hope I'm wrong.

The misery of implementing RCS is what pushed the Matrix team into creating Matrix.

We’re now also working on the identity interop points that ekr highlights.

Interesting! Is there anything public written up about this origin story?
