I wonder how honest Dustin was to Ben and Dom. It's entirely possible that his negative feelings about each product helped drive it further. Sometimes criticism is more important than praise. I would rather someone call my product stupid - and point out why - than to just say, "Yea, it's okay I guess."
To Ben and Dom's credit, I have a feeling both saw Dustin's apathy, read it correctly as apathy, and used that to either strengthen their products, or their story, or both.
