I see an inordinate amount of vitriol directed at him online. I assume it's mostly jealousy. He built a monster product that in hindsight seems very obvious, and you didn't.
- Multiple claims of outright dishonest behavior and undue credit-taking entitlement from his co-founders (even prior to the lawsuits)
- His extremely privileged background. Given his family's political connections, wealth, ivy-league legacy, and prep-school pedigree, he risked very little (compared to most entrepreneurs) when giving a pre-undergrad start-up a go.
It's irrational and wrong, but sadly makes for more "press" and "drama". A prime example is the plethora of rich-kid "reality" t.v. shows which leverage those atavistic reactions it to the hilt.
This is one of my favorite quotes of all time: "It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat." - Teddy Roosevelt
