He wasn’t cancelled. According to Talkers magazine, he got frustrated with SiriusXM’s online player being unreliable as well as SiriusXM satellite and online streaming being unavailable outside of the US and Canada. He wasn’t in complete control of his content, specifically the podcasts which were controlled by SiriusXM. I don’t know why he didn’t think of any of this before he signed an agreement with SXM. Because the online product is subscription based. You have to subscribe to it to hear it. And like the BBC iPlayer in Great Britain, you have to be in the US and Canada (SiriusXM’s market area) to hear it.
It sounded more like he got a cease and desist order from Coast to Coast. He was complaining about sharing guests with them and might have set of alarms with the big dogs. That explains why he won’t restart his type of show. He must have signed a noncompete agreement when he quit coast to coast.
