Yes, and I hope they definitely are listening, because that is one of the most arbitrarily ridiculous "rules" I have ever seen a business put in place. Seriously, do they even watch TV? I don't see how they could possibly think 3 tuners is any shape or form of a "whole-home" solution.
The reason only 2% have multiple Hoppers is that is the non-tech-savvy folks who simply listen to what an uninformed Dish CSR tells them they need. If a true needs analysis were done with each person, I'm sure a lot more would have multiple Hoppers (and probably be a whole lot happier with their equipment). They just think they can record six things at once so they should be fine. Until reality sets in later when all the tuner conflicts begin. That's a sure-fire way to disappoint a lot of people with their new equipment and send them off to the competition where they can get many more tuners.
Hopper/Joey is a great concept, I have no idea why they are so intent on handicapping it in that way.
