This comes up a lot... but the fact is that OTA is given free via OTA only. IF you want it via some other method, you have to pay. IF you have to pay Dish, DirecTV, or cable then why shouldn't they have to pay for permission to retransmit? OTA isn't in the public domain... you don't have the right to re-transmit and especially not to sell those re-transmissions without explicit permission. Some channels opt for "must carry" which means they cannot charge for re-transmission. Others opt to get a piece of the pie that the SAT/cable companies are charging.
