Customers do not have to get in a contract. That is solely a choice of the customer. They can purchase all the equipment and leave whenever they would like. The contract protects the investment the company made into the customer. There is a reason the contract is not dependent on price or channel selection. It is based on service availability upon installation. That is why there is also a clause that moving does not void the contract. Dish made the investment in the initial installation and proven service could be provided there. They don't sell any channel. They sell packages, and those are sold as subject to change.
