Please stop throwing around Gates as an example of "working for humankind". His charitable work begun only very recently. Before that, he was a cold and ruthless money making machine.
In any case, he was a billionaire several times over by then. The MS IPO was over 30 years ago.
Edit: Now that I re-read my comment, I come off as an arrogant prick. Sorry about that.
All I really meant to say was that setting up a foundation != charitable work. Any poor guy - like me for example - can setup a foundation, but it will only exist on paper.
Maybe you should start your foundation today rather than complaining that others don't do enough on an internet forum. One of those is more productive than the other.
"Before that, he was a cold and ruthless money making machine."
The world is going to suffer for decades under the proprietary NSA infected umbrella of his software. His ruthless machine lives on without him, he never turned it off.
Just wait and see, all this open sourcing from MS will increase and many will fall for the trap (embrace/extend), and then when the days of extenquish come around those of us who took the effort to transition to FOSS ecosystems will be far ahead of the game.
RMS is right. You either control the program or the program controls you.
