B marketing actually annoys the shit out of me if I'm in the market for a product and all of the competitors act like Im not trying to choose between them.
Seriously, who researches buying a dishwasher and wants to hear about all of the time you'd save not washing your plates by hand?
You being on HN itself makes you a minority in opinion. People absolutely want to hear about the time it saves, especially if they never had a dishwasher, and only then when they know of the benefits will they want to discriminate by feature set to decide which one to buy, exactly as the parent comment said with regards to the truck example.
