Jobs was a gifted promoter whose public speaking style tilted casual, informal, and personable. He was effective in part because, at least on stage, he made you like him.
Lots of people are likable, and when they die we don't mourn them, because we never think about them. But Jobs forced people to think about him, because he was the public face of a blockbuster series of products that people talked about year-round. It's not that launching those products was so praiseworthy that it "earned" him a mourning. It's that the combination of his on-stage personality and the popularity of those products more or less forced us to.
That's not a bad thing, by the way. I think there's something human and basically nourishing about thinking about strangers as people, and constructing even a fabricated, artificial form of empathy for what they and their loved ones are going through. That those emotions have no practical connection to the world we live in is irrelevant.
