"Fair use is an "affirmative defense", meaning that you only get to use it as a defense in a court of law after someone has sued you for copyright infringement. And the judge in the case gets to decide if, in fact, your copyright infringement is permissible under fair use." Agreed, and think it can be safely assumed that in this situation that it was easier and more lucrative for him to avoid the hassle of going to court and fighting injunctions against his entire channel, than to simply allow the video to be taken down. Agreed? Also in order to win a copyright infringement case the holder would have to prove the reviewer infringed upon their rights. What legal rights defined by copyright law do reviewers infringe upon? "Reviews of products, such as those "reviews" done by MxR, are protected under the law, specifically the "Consumer Review Fairness Act", but the law only restricts companies from using contract law to "bars or restricts the ability of a person who is a party to that contract to review a company's products, services, or conduct". But the law doesn't say that the company can't disallow monetization of said reviews, which is what MxR does (and constantly complains about as well)." I'm not sure it has to. In what industry do reviewers not get paid for their services? From Angie's list to Top Gear, reviewers have been earning substantial income for reviewing and entertaining their audiences. I don't know what the legalities are, but it's clearly a common practice and has been for a very long time.
