So, I think this article is specious as well. I find that I rarely work with mean people, but that's because
when someone is mean to me, I refuse to work with them. I assume that PG probably does the same thing (particularly if Jessica has the nose for character that the article says she does), and so the article could be entitled "PG is not a masochistic idiot". The same conclusion holds for
anyone who has the freedom of who they associate with - the only people who regularly come in contact with mean people are those who have no means of escaping them, i.e. children, people who are so mean themselves that no nice person wants to associate with them, and people who are forced into a single position for economic reasons.
But I also think that most of the comments on this article are specious as well. It's silly to argue about whether Bill Gates is naughty or nice - you will never agree, and the comments you get say more about the worldviews and experiences of the people commenting than about Bill Gates.
I was once talking to a psychologist I know about corporate CEOs, and she said that there've been meta-analyses done in the psychological literature about what traits make a good leader. And what they found is that across the whole body of the field, 1000s of studies, there was zero correlation between any personality trait and leadership. What they did find, however, was that there was a strong correlation between the personality traits possessed by the study's author and the personality traits they found in the leaders they studied. In other words, everybody saw themselves in leaders. Smart people looked at famous figures and said "They're all of above-average IQ", ignoring the counterexamples that are really quite dumb. Determined people looked at leaders and said "They're all really determined", ignoring the ones that lucked into their positions. Folks who were afraid to take a leadership position projected their inadequacies onto leaders and claimed they were lucky, or sociopathic, or had other reasons why they themselves would never want the position.
Worth keeping in mind when you're reading essays on the Internet about what makes a good founder, or, for that matter, if you're an investor trying to pick out good founders to back. If you're that founder, well, the only trait that all leaders share is that they got someone to follow them.
