Several years ago when I was a little interested in the whole concept I read into the articles but I haven’t looked into these things since. It’s just what I remember from reading them years ago (around 2016) - that vulnerabilities in the tor browser have been exploited by feds, that they’ve managed to infiltrate nodes or some such, things like that. But the articles are probably still up there for anyone who’s genuinely interested in this
The 2000s design is not distracting :)
