Can't say I blame you ady. It's gotten out of hand. Don't these companies realize that youtube is free promotion? Sorry you can't make a dime on every single view like you wish you could, Sony/NBC/etc., but what you're getting is exposure. Nobody is bootlegging youtube videos and selling them in Chinatown. (Are they?)
I seem to remember CBS recently removed one of its own videos because it infringed its own copyright, or something ridiculous like that.
