I fail to understand why people think that YouTube is a charity service. They are a business and act like one, you'd do the same if someone threatens your business.
The problem is that YouTube/google want "le beurre, l’argent du beurre, et le sourire de la crémière".
They want to (and are managing) to distort the openness of the web: they provide free access to a service, the way the web intended to be; but don't want people to use the tools in the way they are meant to be used.
If they want to charge for the service, fine, it's their prerogative but don't blame the users for using the tools as they are meant to be used.
Why don't they stop free aceess? They can, no one is stopping them from doing business that way.
Because they want everything, that's why. When will their "business" stop? What's the end goal?
