On top of page two of the article Bill Gates is mentioned...
"Two proponents of this new legislation are Corbis and Getty Images. They are large stock photo and stock art companies. They sell art and photos inexpensively and are trying to build giant royalty-free databases. Do you see how they could benefit from considering most works of art in the world orphans?
Do you know who owns Corbis? Bill Gates. He doesn't do anything unless it can make a huge amount of money. Helping you lose the copyright to your art is big business for Gates."
Edit:
Another blog refutes his arguments...
