The Murdocks have billions upon billions. If they want to weather the storm, they can. So it's doubtful that they are even injured a little bit. Also, my bet is that the loyal followers will continue to watch them. So while there is probably a bit of a sting, it won't cause them to go down..... At least I don't think so.
My experience is that sometimes/often the wealthiest dislike giving up a single extra cent more than anyone. I don't care how much Murdoch has 'on paper' - damages of 100's Millions is going to hurt no matter what.
