Are there any apps that support RCS that aren’t made by Google or a crappy cellular provider (ie: bloatware Verizon apps)?
I appreciate the features RCS has, but I’d love to get that without sending it all to Google with a “trust us” approach to backdoor keys. The documentation I looked at indicated that anyone could setup an app to support RCS and communicate with Google’s RCS users, but I can’t find any apps that actually do that.
Also would love to be able to message from multiple devices using RCS, which Google has working in their web app.
Matrix doesn’t have forward secrecy, and signal is not proprietary, it’s free and open source,
And Matrix does not fall back to SMS (unless someone implements such a Matrix client).
It would also be silly to try to get everyone you know to use YOUR Matrix client, or one compatible with it.
Signal removed SMS support a while ago…
Indeed, making it ineligible as an alternative to RCS or iMessage
