> Agreed that there are going to be interop issues with Google's RCS implementation, but let's not place all the blame at Google's feet, here.

I have no love for the carriers but to me open would sound like things Google could do unilaterally:

* Android developers can now use the RCS APIs, not just our own app

* Our extensions are released as an open standard waiving any IP litigation except in self-defense

* Our E2EE key server is open to users of other apps and/or supports this federation protocol
