He later spoke in defense of Stern during the latter's legal dispute with CBS over promoting Sirius on-air before his switch to satellite radio. Thompson contended that the technology added by CBS to edit out profanity also could have worked to edit out Stern's references to Sirius. According to Thompson, "The reason why CBS chose not to edit Stern is that Stern's Arbitron ratings remained high and were arguably even enhanced by people tuning in to hear daily about Stern's running feud with CBS and his move to Sirius. In other words, CBS actually used Stern's discussion of his move to Sirius to make more money for CBS."
