From my view, it has nothing to do with what or how many channels get dropped. No one has to have a term commitment with Dish. The customer accepts the contract term in lieu of purchasing the equipment and paying install fees. The term commitment is the customer's choice. It's a calculated risk and classic pay now or pay later scenario.
I somewhat agree, and when you get the Top200 package and Dish drops AMC, you still got 199 other channels to watch.
The issue is when you get an international package, your getting a handfull of specific channels. Take away a single channel like NTV, then thats a significant enough reason not to want to honor your committment.
As someone who has worked with Dish and Directv since 1997, the one thing I have learned is that their contracts with customers mean absolutly nothing. All you need to do is write the BBB, State Attorney General, Department of Justice, or any other Bullsh!t goverment organization that deals with customer relations with companys and plead your case with them.
They will then inturn contact Dish or Directv on your behalf and about 3-4 weeks later you will get a phone call from the provider wanting to see what the issue is and will more than likely let you out of the contract.
Do I agree with getting out of a contract this way? NO
But I have seen it done enough times by other customers, where I am fairly certain you will be able to get out of your contract.
