Do a search on the Bill and Melinda Gates Foundation instead. You'll find thing's such as
this,
this,
this and
this.
I could go on. I found dozens of them. Their foundation mainly funds work in the areas of vaccine research and education; it presently has an, individually funded, endowment of about $24 billion. It has already given away in excess of $6 billion.
The Gates' have declared that their children will be left $10M each, the remainder of their fortune, above and beyond that already donated, will go to the foundation upon their deaths. Whatever else you may think of him, Bill Gates has a strong strong moral awareness of his position and intends his fortune to be spent doing good, he intends to follow the example of past philanthropists such as Andrew Carnegie.
I can think of an awful lot worse places for the money to go, including the pockets of the companies buying/teaming with the major Linux distributors such as Red Hat (Oracle & IBM) and SuSe (Novell).
