Editorialist: Many professional musicians claim that unauthorized music-sharing services, which allow listeners to obtain music for free, rob musicians of royalties. While it is true that musicians are deprived of royalties they deserve, music-sharing services are not to blame since record companies, publishers, managers, and other intermediaries take an inequitably large cut of the revenues from music sales. The reasoning in the editorialist's argument is most vulnerable to criticism on the grounds that the argument ['attacks a position based solely on the character of the people who hold that position', 'attempts to promote a particular behavior simply by showing that many people engage in that behavior', 'treats a necessary condition for blameworthiness as though it were a sufficient condition for blameworthiness', 'concludes that one party is not blameworthy merely because another party is blameworthy']
