If we really want to go in this direction and criticize other people calling famous tech businessmen assholes, at least give credit where it's due - Jobs deserves this much more than Gates. Gates documented unethical behavior was mostly against other companies, not so much individuals, with a few notable exceptions.
I doubt Jobs--who died nearly ten years ago--was as likely a trigger for this essay as Gates, who is currently in the daily news due to his alleged bad behavior.
On the other hand, Gates' recently reported "bad behavior" seems to be largely stuff like infidelity and inappropriate sexual relationships which is not what the essay touches on at all. Jobs' assholery is exactly business & engineering related in the way that PG is talking about.
I wonder how much Bill Gates triggered this write up.
