There is no way Howard could be allowed to "say what he wants" without the station losing its license. Radio content is regulate; Sirius/XM is not.
Second, Howard did well when the ratings were done in the diary system in the largest markets where people wrote in long listening spans. In the PPM, Howard would have ranked much lower due to more precise time measurement and the almost total absence of secondary listener. A calculation I did for LA shows that, instead of #2, Howard would have been around 9th or 10th in share/rating/AQH persons. So Howard would do much, much worse in the PPM than he ever did in the diary system.
