Its the law, not YouTube. Just because you don't ASK before using it to make thousands does not mean you're entitled to keep on making profit off a product that isn't yours. More than likely if you AKSED to make a PROFIT off of someone's product, they'll let you do so after a deal. Which isn't that bad, its called business and its a part of the real world. EDIT: Some of the flagged videos are BS though I admit. However my point still stands for YouTubers such as game commentators.
