They changed their policy, which you agreed they could do at anytime they wish, and gave you advance notice and the opportunity to opt-out.
They could have changed it without notifying people and opted everyone "in" by default. By the time people found out about it, your name is already sold to "x" number of marketers. Even if you then opt-out, it's too late. Granted, Dish won't sell your name anymore, but the others have your name and are selling it, to which you have very little control (mainly, you don't know who they are).
