Here's the confusion: If you look closely at the ad, it doesn't specify who your provider will be. It just lumps a bunch of logos together: HughesNet, ATT, Xfinity, Frontier, Cox and CenturyLink, adding "plus other nationwide providers". All the specs they mention is basically a mashup of everyone's claims, when in fact they say they will find the best bundle available. Note that the disclaimer says "discount offers varies by service address", so I'm sure $39.99 is the maximum discount possible, if available at all.
I'm willing to bet the HN people hate bundle ads like this because it ultimately makes them look like liars, when Dish is the one being deceptive (like most resellers).
