@ArcaneAlchemist it's not "some blog", Soatok is a solid security researcher. Ignore his insight at your own peril.
Also, did you really just argue that surely a certain solution is perfectly fine because nation states use it? Really? :blob0w0:
Because that would make Microsoft Teams by far the best communication solution in the world.
@rysiek @m I'm judging it as a "blog" because of the style of language and the disclaimer at the beginning. I'm not saying Matrix is perfect, but considering that (at least Germany) is actively contributing to it, I expect that they also have experienced security researchers looking at the codebase. To use your argument, why go through all that effort if they could have just used WebEx and Teams? Arguing that the devs and auditors are all incompetent is a bit far fetched, don't you think?
