Google should have to live by the same fair use standards they put on their content creators. Given how ridiculous YouTube and search can be with filtering out content or complying with obviously bogus DMCA take-down requests, Google should also have to comb through their datasets to aggressively apply every complaint. It's only fair!
That is the copyright owners and Google is just giving the message. Google does not own the content in Youtube, the owner of the content make the demand. For google it would be better to have free to all, because there would be more people watching.... so more income to them.
