The guy, who is clearly pretty passionate about his point was responding to a previous statement by Jobs that Java was superior to OpenDoc and hence why OpenDoc was junked. This 'troll' was just calling Steve on a bullshit claim, and rightly so (and rather eloquently, I thought). Steve's considered, honest, respectful and above all direct response was a great counterpoint in turn. Well played, both of them.
I don't think Steve's claims about OpenDoc were bullshit at all, he was totally right that any limited success in that market was Java's to take and that OpenDoc had no chance whatsoever: http://www.youtube.com/watch?v=udyy2gQyNso
But he did directly insult that guy: "I know some of these people, they haven't done anything in 7 years… they leave, and act like the company's going to fall apart the next day…"
