Apple is adopting the Universal profile. If GSMA wants to add E2EE to that profile then they should. I believe that there was some talk of Apple working with GSMA to add or improve encryption on that profile. AFAIK rcs is licensed out to OEMs and so there are a number of different implementations around. In my opinion it would be better for all if there was a secure standard in place - for all to adopt - instead of hoping that everyone works with google to try to get googles proprietary implementation working.
