"5 years after the creation of Matrix, and after 5 years of centrally receiving such a scandalous amount of users private data from their «decentralized» software, it was only after the mentioned report was published when the Matrix developers published some «privacy improvements» [13] addressing some of the revealed problems.

We have not read it."

This seems lazy to me. I haven't read the report but i'm also not the one writing an article bashing matrix. If i was I'd want to know whether my concerns are still valid, and as a reader i want to know whether the concerns they brought up still apply without having to read a whole other report
