Interesting vid. But it certainly doesn't change my view of protecting IP for use on clothing brands. Clothing is a tangible object. If it's knocked off by someone else, whoever buys the knockoff doesn't need the original. So the clothing brand just lost a customer. But when Chris Brown's vid went viral, people still have to buy the song, album or tickets to a concert to see more. There's less risk of losing customers in that scenario. Also, there are differences between allowing copyright usage and allowing trademark usage. A trademark owner can forfeit ownership by not protecting their mark.
