Faulty premise there, though... Dish didn't drop the channels. AMC pulled the feed when the contract was up.
Dish said AMC wanted too much, AMC said Dish refused to negotiate. We only have AMC's "word" that Dish refused to negotiate... but we know AMC pulled the feed at the end of the month.
According to a recently former Dish Network employee, now working at a competing cable company that happens to be my client, Dish Network broke off negotiations weeks before the channel went dark, and there have been no negotiations since then.
Take that for what's it worth...this guy volunteered the information as part of a conversation about how Dish drives hard bargains with content providers. He offered no reason why the negotiations were ended and I didn't ask. He simply said "Yeah, and if they don't budge, <negotiator's name> will just walk away...look at AMC..."
