There's a reason all these stories stay so vague - as soon as the details come out, it turns out to be lies, exaggerations or really really minor stuff.

By keeping the narrative at the level of "fouled up his room", "made women feel uncomfortable", "drove people out of open source" the people who attack him can make sure that no one can prove them "wrong". Of course, they also ensure that they can't prove anything themselves, but it's not really about that.

I guess a good criteria for criticism should at least be something that passes AirBnB editorial review.
