He was much more low-key about the 'products' at Pixar, he mostly was an enabler and negotiator for them. In Pixar's early days he invested an awful lot of his then-fortune into keeping it alive, and it was his cunning negotiation skills that kept Pixar from being swallowed by the then flailing Disney.
If you contrast his behaviour at Pixar and at Disney, I think it illustrates that he didn't consider the work at Pixar to be 'his art'. There were other people at Pixar who were leading the 'art' there and it was all in hand.
At Apple on the other hand, it's completely clear that Jobs' considered the products to be 'his art' and his conviction was such that he literally was going to drag everyone, kicking and screaming, to realise his vision. And that he did, in a world of horrible consumer electronics he would not abide, he set out and truly lead the creation of some very awesome and uncompromising products. It was his Art.
Imagine if Andy Warhol or Piccasso or any other famous artist relied on the expertise of many individuals to realise their creations. Do you think they'd be considering that all you want is your 9-5 job and your 401k and 4 weeks holiday a year. Nope, they'd be behaving in exactly the same way: aggressive and fervent conviction. Work ceases to become merely a job and you're no longer working, you're crusading.
In a world of unambitious and mediocre individuals, you have to move mountains to do great work that requires multi-disciplined collaboration. You're going to upset people along the way but that just comes with the territory.
I don't think it's fair to blame him for his behaviour. The world needs more people like him: true leaders who will stand up for their convictions, no matter what the cost.
