Why is it hypocritical to cut a deal with certain important clients? Even Stallman recommends selling license exceptions to GPL'd code.
Generally speaking, any startup on this site will give preferential treatment to a $50,000/month customer than to a $5/month customer.
Even your bank will treat you differently if you want to open an account with a deposit of $2 million than if you want to deposit $25.
I don't think "hypocritical" is the right word, since Youtube isn't making a moral judgment. They'd take any money they could if their partners would let them.
