Yes, the criticisms are generally valid. However, if the only proposed alternatives are Matrix, XMPP, Briar and Jitsi then Signal is still the best messenger. O

Yes, the criticisms are generally valid. However, if the only proposed alternatives are Matrix, XMPP, Briar and Jitsi then Signal is still the best messenger. Of course those alternatives are great but for 99% of the people they are way too complicated. I think what Signal should do, is set up additional multiple servers in the EU and maybe add some kind of noise messages to make it harder to analyze the meta-data/social-graph. People/Groups/Firms who need more security should probably switch to Matrix.
