Oh my God!
Well, they have the server infrastructure to pay for all the bandwidth... and sell ads on their site (YouTube generates their revenues off Google's back in the first place). The lawsuits issue.. I find that most companies would rather opt to work with Google than YouTube management, because once its under their wings, YouTube will no longer be a "bad guy" in show biz.

I tell you one thing, YouTube suger-daddies are going to be very happy.
