It seems that Bill Gates himself is a fan of piracy. He supports it just like millions of other people through the use of sites like YouTube.
Now this is far more difficult to stop than even movies, software, or music on hard media, this is out in the open, share with everyone, piracy.
Its easy to get, impossible to pay for and pointless to report. If Bill, the richest guy I've ever met, enjoys it, why the heck am i trying to stop piracy around me?
