This isn't about the privacy tech. This is about Uber being evil, knowing that they are doing evil, and trying to hide their evil from the courts. The fact that they worked at a high level to hide their evil destroys any pretense that it was accidental or unintentional.

But seriously, it's a bit of a catch-22; engaging in privacy preserving behaviour but later falling under suspicion of some illegal act shouldn't imply that you engaged in those behaviours for the intent of covering up suspected but not proven illegal acts. It's a real issue -- but it someone were so stupid as to say "haha, I did x so you couldn't prove it!" ... well, that's basically an admission of guilt, isn't it.
(There's another issue here about normal everyday things being painted as unusual and bad. I think that that's what drove the post that I originally responded to, and I can't fault the overreaction - too many people have in seriousness said things like "if you have nothing to hide". For the listed reasons, however, I don't think that that's what's going on here, and I'd prefer to avoid giving the anti-privacy group ammunition in the form of weak arguments.)
