Chef In Charge of His Decision to Quit South Park?

Isaac Hayes has quit South Park reportedly over the cartoons lampooning of Scientology, which Hayes is a member of. However per Fox & Roger Friedman, someone maybe controlling Hayes' decision here:

Isaac Hayes did not quit "South Park." My sources say that someone quit it for him. I can tell you that Hayes is in no position to have quit anything. Contrary to news reports, the great writer, singer and musician suffered a stroke on Jan. 17. At the time it was said that he was hospitalized and suffering from exhaustion.

If the church is having undo influence over Hayes' decision to leave the show while in the reported medical condition, it's not hard to see a very ripe and hilarious new episode coming soon from South Park. Maybe titled "Chef & His Chocolate Salty Balls get Abducted by Tom, John, and the Church"....................Funnier than fiction................
