The KEY points in your post are the fact that this does NOT affect 721 receivers that are already "in the field" activated and installed. This only affects DISH not being able to deploy any more into the field. NO WHERE does it say CUSTOMERS are barred from using, deactivating or reactivating receivers that they already own -- if it did, I'm pretty sure the customers would have received some notice from Dish or a court about this. Therefore, it's OPEN to interpretation. Therefore, I WILL go with Dish's interpretation of said order.
This "error" is only in the eye of the beholder at this point.
And the rest of us will also go with the new interpretation now as well. We asked this question to Dish. We got a different answer a few weeks ago. This is the first instance we have seen of a 721 being successfully transferred. Am I suurprised that DISH reversed themselves? Not really. They seem to be pushing the courts a lot recently.
BTW, I would bet you would get a different answer if you tried to activate a used 921 or 942 as Dish wants those MPEG-2 HD units out of their system.
