I don't know how mucher later, but this guy killed himself afterwards. Linus told that he doesn't feel guilty about this or thinks that he was the main cause for the killing, but well, I don't think that such an experience has no effect on your behaviour, but I can't tell if Linus' behaviour was different before this event.
I think that Linus told this story in the talk where he showed nvidia the finger.
I actually find his reasons quite convincing, I think he's got a point.
That would be a classic symptom of narcissism. I'm not saying Linus is a narcissist, if anything I'm saying the opposite -- if he accepts the same treatment from others that he puts out, that argues against narcissism.
Now Steve Jobs, on the other hand ... I couldn't stand working with Steve because of his obvious and unbearable narcissism. He is why I never worked directly at Apple for more than a few weeks during many years of professional association on a number of software projects.
