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.
Signals server software is open source. I suspect you mean the main signal network is closed and centrally controlled (it’s not federated basically) - anyone can run a private signal server (and network) but not as a node within the main signal network is my understanding.
Maybe they meant that at some point a few years ago Signal didn’t update their public open source server code for neraly a year or so while simultaneously rolling out new features.
