Government regulation of cable companies can be somewhat justified by the "utility" model. A consumer is likely to be bound by the physical infrastructure in choosing a provider. Satellite companies have no such power over customers. They offer a product for sale that you can buy or not buy. Their pricing model should be none of the Government's business. A merger between Dish and DirecTV might just open that door to additional interference in our lives.
If you are paying $150 a month with multiple TVs, and are demanding lower cost per TV, you are simply, selfishly, demanding that customers with fewer TVs subsidize your viewing. The satellite company needs to make a profit. The total cost for all customers still needs to be the same.
