If I were Dish I would not return the channel until Fox dismisses all legal action on the Hopper and comes to reasonable terms on all other contracts coming due soon.
I agree with you on this. Dish could say, yeah, lets renegotiate the rates for the other channels, how about getting paid "LESS" for them instead of more. When the contract comes due for the other channels Fox could say that they want Fox News renegotiated, the flipside of what they are wanting to do now. It might be in their best interest to negotiate everything now and make sure it is all reasonable before returning Fox News but if they change contracts to make them all due at the same time then that will be very bad news as they will try to hold all the channels hostage as other companies already do.
