Why would you wear glasses to watch normal programming? You only need them when watching 3D.
I realize it's a lot of fun to put down stuff that is new. Perhaps the people doing it just bought TV's recently without 3D, so they need to feel like they aren't missing anything. Or, maybe they just aren't planning on buying a new TV for a while, and need to feel like they aren't missing anything. Or, they just wanna save money, and plan on buying one of the few non-3D models out now because they are dirt cheap, and they need to feel that they aren't missing anything. Of course, it could just be the usual case of Dish apologists who defend whatever dopey decisions Dish makes.
But, the fact of the matter is that the majority, or at least a huge number, of the new TV models from all of the major TV brands are 3D-capable. And, the people who own them would like some 3D programming to watch, even with those stupid glasses. That is why Comcast, FiOS, and DirecTV all provide a fair amount of 3D programming. If there was no audience for it, they would not be spending the money to provide it.
Nobody wants to watch 3D all of the time, especially with glasses. But, it would be nice to have a couple of full-time 3D channels and on-demand programming available, instead of the couple three PPV's that Dish provides. It's a perfectly valid desire.
