With a highly-anticipated ruling in what has become known as the "dancing-baby case" delivered on Monday, the Ninth Circuit Court of Appeals affirmed the importance of allowing for the "brief, non-commercial use" of copyrighted material by saying copyright holders must consider whether or not such use would be considered 'Fair Use' before issuing takedown notices to third-party hosting platforms like YouTube or social media outfits.
A foolish consistency is the hobgoblin of little minds.-- Emerson
While in this case it was Universal being the jerks, Prince is famous for being exceptionally dickish about his music and how it's used. He even demanded takedown of videos where he's performing another band's song.
Copyright used to be about protecting the right to copy a work and make money on it so that it lessened the ability of the creator of the work to benefit from copies and it very clearly allowed for fair use but in recent years, it's almost the same as patent which has always been a blanket bar against anyone else infringing on it for any reason and regardless of any harm.
