Why didn’t Steve Jobs do philanthropy?

Because he is ruthless and greedy. In his youth, Steve Jobs himself was not a great god, at least not a god in terms of charity. Because that's the kind of person he is. His character is: stingy and greedy for petty gains. I would like to ask such a stingy person, would he donate his own money? At least I can't see him or Apple Inc. donating their own money or showing their charity.
