My mother had one receiver on her account that DiSH insisted was leased (although my recollection was that we paid the dealer for all three of her receivers). After she passed away, I returned the one additional receiver to them. They provided the label, there were no additional charges. It wasn't a "sympathy" thing on their part, as they never even asked why I was cancelling (which I thought was a bit strange, but didn't think much about it given that there were other things on my mind).
Late last year, a friend of mine that I had referred to DiSH gave up after having a number of bad customer service experiences. I helped her switch to TimeWarner, order her CableCards, and get the TiVo boxes setup and connected. After the cable installation, I called DiSH to cancel for her and was told she'd be paying the $30 for shipping her two receivers back. (The representative also insisted I would need to climb up on the roof and get the LNB, as well, which was something I'd never heard of anyone being told to do before.) The supervisor I spoke with said the shipping fees were implemented earlier in 2010. I asked for the nearest local dropoff location and was told DiSH no longer allowed equipment to be returned to their authorized representatives. I told her I thought it was disappointing for them to slip the fee in like that, and essentially hold customers hostage with the threat of a non-return fee unless the "official" label was used. (I've read the horror stories of folks returning equipment, even by trackable means, only to be charged non-return fees anyway.)
After telling her I'd be happy to pay for shipping to their corporate offices, along with my equipment and a letter requesting cancellation of my account as well, she agreed to waive the fees for my friend. After putting me on hold for over fifteen minutes, she also came back and said they'd "waive" the return of the LNB. When I told her it'd be the last time I refer anyone to DiSH until they fix their customer service problems, I meant it.
(As an aside, having had a fair bit experience with logistics and the bigger couriers in the United States and Canada, I'm sure a company of DiSH's shipping volume doesn't pay even half of that $15, at least not for ground shipping. Not that the shipping cost in and of itself is the only expense in handling returned equipment by any stretch of the imagination, but it's certainly my experience that DiSH is the only company that charges for that return shipping -- and, as noted, they didn't do this for the first fifteen-plus years of their DBS-existence. I think most companies regard return shipping simply a cost of doing business where leased equipment is involved. I'd guess the higher churn back in 2009 and early 2010 was probably the reason for this "cost-cutting" measure.)
