Ehhh.. He has a universe of shows on that channel, I'm sure he can influence it to stay for another year if he wanted to. If not, why would they sign up for spin offs
I wouldn't deny him having influence.
But the notion of him, himself, having the capacity to shut down a full ass major production full of all kinds of contracts of not only actors but staffing agencies, equipment rentals , and management, insurance , filming permits etc etc all because someone pissed him off is Hollywierd smoke and mirrors. That level of the game aint on his call
