I was on the beta testing team and have been using Beeper for a little over two years now.
The convenience of having an application to house all of your chat networks is amazing.
That’s fine… for you, right now.
But I (and probably most users) don’t know them, over time people come and go, some even change who they are, businesses get sold. Only open source persists.
Thankfully all of the Matrix bridges they created for Beeper are open source.
