alt Hacker NewsI wouldn't be particularly surprised if they're hiding the spec / charging pointless $$$ to reduce access, but I was under the impression that it would be available, like RCS's spec itself. e.g.:
the RCS v3 page: https://www.gsma.com/solutions-and-impact/technologies/netwo...
^ which links to the E2EE v1 spec: https://www.gsma.com/solutions-and-impact/technologies/netwo... ("download" is a direct link to a pdf file)
and https://media.gsma.com/assets/2026/rcs/RCC.16+v3.0.pdf is v3.0, which appears possibly detailed enough at a glance, and there seems to be a v4 and I can't download v2 due to a broken page. but I have no idea what's currently supported anywhere in practice, if any.
Ah when I last checked the E2EE was only in practice implemented by Google and invented by them. It looks like this might have been opened up, unless this is an earlier version somehow? And interconnect traffic to e.g. iMessage was not E2EE.
I have to look up on this again as the last time I looked at it was during late corona (2022? 2023?) when there was a local talk to adopt RCS (which failed)
But the problem remains that they simply won't talk to you if you set up your own server. You have to be in a select club to be able to run one.
It's very unlikely I'll ever switch it on because I don't use any google account on my Android and I don't trust them nor the carriers for reasons I've clarified in the other posts in this thread.
