He was a major asshole, however he was very good at running tech companies and managing tech products. That's why people drool over him. Watch the YouTube videos from his Next days, and show me a corporate CEO on that level of competence and involvement who's not an asshole.

At least in his case, he was an asshole who actually made something good - not apologizing it, but in most cases it's assholes making up bullshit just to be assholes. Jobs made his employees a lot of money through Apple stock, others usually just take your life force and money away.
