All the times that you said he was just being harsh, I'm sure the people who were impacted thought he crossed the line as well.
Whatever the truth of this PERSONAL conflict, which by the way is peripheral and inconsequential (except for negative consequences) to the issue of the crisis at Airbnb, you're not doing your professional self or the company any favors by continuing along this line of commentary. Emotions are influencing your behavior in areas where rationality would better suit your situation. Better to quit taking things personally and focus on taking care of the business at hand.
Is your contention that this is not what happened? If this is what happened, then I think you owe Michael an apology. He has done an excellent job of updating his article with more information from airbnb's side of things as he got it, and I think that if you misspoke or were misinformed you need to say as much.
On the other hand, I still don't believe he's deeply evil. His big weakness is the length he'll go to to get information out of people. I think he crossed the line in this case. But I still don't think he's a bad person.
