In 9 out of 10 disputes, I would see where Claude is coming from. If TBS was pulled, I'd get it. But why for the need of a set subscriber amount for a channel where the subscriber basically pays the channel direct? That should be it! If 100 people sub to HBO, then AT&T gets paid for those 100 people. If 1 million people sub, then AT&T gets paid for the million. It's not up to Dish or any provider to cover a set cost, nor is it up to them to get AT&T subs for HBO. You want subs for your premium? Do the work to get them!
Again if this was a basic channel, I would be singing a different tune. It's a premium channel, or two premium networks to be exact. In essence, Dish isn't rewarded for HBO subs. Dish is rewarded for basic channel subs, but not premium be it HBO, Cinemax, Showtime, Starz, or EPIX. Those revenue goes straight to the channel owners.
