I am not comfortable that signal depends proprietary google library. However, I find that Molly lags significantly behind signal (around 1 to 2 weeks, so maybe not as significant as I thought), but I am just concerned that if there is a security fix in signal, molly will not be able to react as fast.
I am also quite frustrated with the general lack of communication from the signal team (for example the lack of communication regarding username). I doubt they will have the good will to help molly when there is a critical security fix.
It is frustrating that signal no longer seems like the gold standard for privacy any more; unfortunately, all my friends are on there (ironic, isn’t it…).
XMPP or Matrix. I’m on Matrix only because I have my family there and I was there before I knew of XMPP and at this point I can’t turn that boat.
Signal was/is (idk if they still are) into crypto, they don’t let you run your own server or client, and they have a proprietary shim in place to combat spam (or so they say, it can’t be audited because it’s proprietary).
I was all in on Signal until the above.
