Of course it's true. Steve Jobs was a huge D, and egomaniacal narcissist and sociopath to boot. Yeah, he had a magnetic personality - just watch the 2005 commencement address he did at Stanford for an example of just how well spoken and charming he could be (it's available on youtube) - but he was still a huge D. And even at his very best his narcissism was still there - in that very same commencement speech he tells an anecdote about how his cancer doctor allegedly cried when he found out that The Great Steve Jobs was cured of his pancreatic cancer. That almost certainly never happened I'm wagering.
The tales of him blowing people off for little or no reason (giving rise to the probably urban legend of how he fired a guy in an elevator who didn't even work at Apple, and so on), his 'reality distortion field' where he would claim ideas of others that he had previously dismissed as stupid or bad as his own, or that time he cheated Steve Wozniak out of something like US$1650 (1970s dollars btw), or you know, the whole "you're holding it wrong" thing... There's so many examples of Jobs being an abusive D; him disowning his own daughter is just one in a long line. Why he's being held up as the 2nd coming by so many Apple fans is rather beyond me.
Yeah, he was influential and even inspirational at times, but he was also a huge D. And most likely the reason he's dead now is because he was a fool who believed in 'alternative medicine' despite having been a computer industry leader for decades.
