His use of others copyrighted content falls under fair use since he's doing reviews. It's YouTube and mega corporations fucking over and taking country the laws. Fair use does not mandate the original copyright owner be paid in anyway.
But it's precisely because YouTube is a megacorp attached to another megacorp that Jim can even upload videos without paying for distribution.
YouTube and these other companies should follow the law.
And I support strategies, such as this one, that forces these companies to follow the law.
