Dave said on his podcast that basically Sirius asks for too much time and not enough money. They have almost the same ratings as Stern but don't want to offer even close to what they offered Stern. And they want Dave to have his own show 4 days a week and with how much he is doing right now and travelling, it wouldn't make sense for how little they are offering. I wouldn't be shocked if they went to Spotify. They have been buying up a lot of the podcast/radio content and for the most part leaves the creators alone.
