I’d suggest looking in to it farther. The commenter above basically covered it, but no, beeper is not all closed source. Their hosted server has never been open source, but all the self-hosted bridges have been, and continue to be. You can run your own, open source, self-hosted beeper server, just like you’ve always been able to. There’s nothing embrace, extend extinguish about that.
