Whoops! Now that really was news to me. I default to closed source for profit and this was the first time I got it completely wrong. Sorry and thanks for correcting me.

But I already told you I have no knowledge of signal. So I guess my fault was to jump to this conclusion when prompted.

But now I have to ask. How does the backend of signal work? I just saw the frontend/client to download but I cant remember there being servers. How do you find your grandma on signal? That must be going to some kind of server, right? Also, signal got hacked at some point and lost 10k+ phone numbers of users which is unfortunate. And there is the benefit of matrix again. You can host your own server with your 10 friends and as long as you update regularly, you‘re a very bad target (small and up to date).

I think matrix is absolutely not at the stage where you can compare it to something as polished as signal. I just checked wikipedia and they made 8 digits a year. So, I get that they‘re not making billions and not selling data but people „work“ there in stark opposition to matrix (bar element). I‘ll say that signal is probably a very good product and overall trustworthy. Although I have to say that it’s not a competitor to discord, unlike matrix. Which was my actual claim.
