I mention the above to state only one thing... Practically everyone here does not know enough about Gates or Jobs on a personal level to make any kind of judgement. Anything you hear is all second hand information and what is displayed by the media. It could well be, relative to a lot of other rich folks, Jobs didn't play a big enough role and certainly Apple was not involved in any charity related stuff, but that doesn't mean he hasn't done his part towards causes he wanted to help out.
Metaphorically speaking, it's a lot like saying someone who has money but doesn't buy much is cheap. That's not necessarily true. They'll spend money, and lots of it, on things they actually care for and want. On other things, its not important. On this front, Jobs also is an example. All that said, it's their life, their money. Let them choose how to live it their way.
As another HN member already commented, don't idolize either but take away lessons from each and mold your own path.
