Ouch, that's a popular position to have in the MacRumors Forums....but I'll bite.
There is no argument that his philanthrpy is a good thing. The argument is that ill gotten money distributed freely is not exactly philanthropic. Of course, you don't seem to follow this simple discussion, so I'll make it painfully simple for you.
Let's say that I stole a guy's wallet and give that money to the American Red Cross for hurricane relief. Does that make me a good person? Well, yes since I gave money, but more importantly, no since I gave money that was not mine in the first place.
Of course this all presupposes that Bill did steal the OS....which he did. If you want to argue otherwise, go find another place to do it, like a corner.
Finally, saying we don't have lives when the topic of discussion is Bill Gates is a bit ironic. Remember, this man learned how to do what he did by spending days on end working on a mainframe his school's PTA got access to. This was, as you may know, to the point where he would come out splattered in pizza sauce from the past several meals. So, I guess in a way saying we don't have lives is a complement, since hey who knows, you might end up working for us someday.
Have a nice day.
