A bunch of years ago I recommended against the use of the Session messenger (a Signal fork) but that wasn’t due to its technical merits. I found it concerning what kind of audience that messenger addresses. If the app is geared towards white nationalists, sexists and the like, then nobody else should help improve its image with their presence. Mind you, that was a long time ago and I don’t know whether they’ve improved.
But @soatok took apart their cryptographic approach now and… well, I better just quote him:
“run, screaming, in the other direction from Session.”
Yes, it’s that bad.
