Otherwise known as survivorship bias. Jobs was an asshole etc who happened to turn out ti be right. It's virtually impossible to know in advance which asshole will be proven right and which won't.
Jobs' legacy on the behaviour of so many future companies will be an interesting one, because some people only looked at that one side, and ran with it.
I'm not saying Jobs was not smart - but chance and luck was a huge factor in his successes. He wouldn't have had his come-back had Apple bought BeOS rather than Next.
