Matrix as a protocol, and synapse / element, the most common backend and client for the protocol (I believe), have existed for quite some time. Our co-op has been using synapse for about a year and a half now and I'm sure the majority of our members use Element as the client. Our managed hosting comes with an Element web deployment as well.
We used it as a drop in replacement for slack including automations etc. The bonus was we got, I can't remember the technical term but mirrors or duplicators for Instagram etc set up, so people can use the element app to message people on Instagram, Whatsapp, etc, if they'd like. I like it because I can message people without Instagram first trying to suck me in with Algo bs.
