You list examples but don’t cite any references to prove that these people didn’t make substantial philanthropic contributions. Nor do you cite counter-examples like those other commenters have mentioned. Andrew Carnegie, the richest person of his era, donated 90% of his wealth to philanthropic causes, most notably to local libraries, universities and scientific reasearch. He implored his fellow wealthy people to to the same, believing the only worthwhile purpose for accumulating wealth was to reinvest it in improving society. The Rockefellers seemed to do the same, as have many others since. In Patrick’s case, his company is still in growth phase and his wealth is mostly on paper, so he’s not able to give much time or money. I’m sure he will when his company’s success becomes more assured and he can spare the time and money. His friend, YC President Sam Altman, has donated $10M of his own money to YC Research to help find answers to hard questions he cares about, which I think is a lot for him (I was surprised to learn he even had that amount to spare as his own company wasn’t a huge success).
