Nope, Dish is right.
Sling (and Nomad from D*), just taking the DVR portable. So if Fox is right on that, then every DVR out there would need to be shut down too. I'm sure you can't wait for that to happen.
As to your rant on Dish's implementation of MOCA. Not much difference between what D* is doing from a wiring standpoint. Major difference is that from the dish to the Node (or splitter in D*'s case), Dish uses more than one. From there on it is one cable to one box. D*'s only benefit in the wiring is that in SOME cases you can split again at other places. I'm not sure that is a big plus.
And having watched the software downloads on D* and E*, software downloads just aren't a big difference at all.
