Just thinking big picture here, and again...not in any formal capacity for my employer, but if this starts becoming an issue, I see changes. Maybe it's a tiny amount of cases, but in my loyalty days, I took quite a few of these.
I suspect that if it happens enough, and enough people make a big deal of it, Dish could, at some point, stop giving free installations. They may start charging for them. As people have noted, it does cost Dish money to do an initial install. Then, Dish makes no money (generally, although I have zero evidence of it) during the first 12 months of severely discounted service. And it seems so many of these move/NLOS calls come near the end of that first year, I see Dish moving away from free installs. Or perhaps adding a rider saying they'll waive the ETF, but that the customer will be responsible for the cost of the initial install.
Dish spends a few hundred to install service. Dish then makes no money for 12 months. Then the customer wants out. Dish just lost a lot of money on that deal. I'm not talking what is right or wrong, it's been discussed to death in the thread. I'm just saying from a business angle, that Dish isn't going to roll over and lose money on these deals if they happen a lot. Dish used to waive the ETF due to mover's and NLOS, and started looking at the balance books due to it.
Again, the disclaimer in my sig...I am presenting my own opinions. Period.
