Have you ever actually met any of these people in real life? Reading headlines about famous people doesn't mean you actually know them.
My point is that questionable behavior didn't oust him initially compared to it being a fundamental disagreement over the direction of the company.
I'm sure the behavior didn't help, but if they were still making money hand over fist, the board wasn't going to turn around and say "you're too much of a dick so we're ousting you".
Being a dick screws over motivation, colleague happiness/satisfaction, increases turnover, etc. These things have an economic cost. Being a dick can cost your workplace lots of money.
Look at how badly Jobs treated his subordinates and family for an actual criticism of him.
