      E2E on RCS is not a described standard. This is a google addon that requires the use of data/WiFi to function, and is exclusive to the Google Messages App because Samsung torpedoed their own app last year, leaving Google as the only E2E “provider”

      spoiler

      Functionally, it’s not even straight RCS because it bypasses the protocol limitations by using wifi anyway.

      At that point, it would be equivalent to using Signal or Whatsapp since they don’t run on GSMA either.

      To be fair though, I guess this is also partially GSMA’s fault for not properly creating a guideline for an updated standard or version.
