I hope DIRECTV® shows restraint in this. The shoe will soon enough be on the other foot, and sat services should be railing against cable, not each other.
Just saw a commercial a few minutes ago by D* claiming AMC as one of the channels "gone" from Dish.
So it's already started.
But it's competition, they aren't in business together. To them Dish is as big a threat as cable, bigger in some markets.
