Gabriel Rossman uses the Dixie Chicks incident of when they openly spoke out against Bush to show how synergy is creating corporate censorhip.  Companies like Clear Channel may not be as quick to black list the Dixie Chicks, but when they do, they can eliminate radio play, concert advertising, the concerts themselves, and future success.  This correlates with the media conglomerates directing the audience what to like, thus a move from fandom to fadism.
