You're just justifying your actions. YouTube is not free to run, and the content there is not free to create. You're a parasite.
Don't worry, I'm as well - but be honest about it. What you're doing, and many other gigabrains here, is just pathetic. There is a lot of corporate greed in this world, but this ain't it.
You're really spending a lot of energy calling piracy not piracy.
