I hate dishonest marketing as much as the next person but I don't think it's a stretch to say that there is nothing wrong with telling a good story about a product. And of course, telling that story means de-emphasizing unpleasant tradeoffs, and emphasizing pleasant ones. The ultimate concise version of this would be a list of features. That wouldn't be nearly as exciting or informative, would it? (I recognize that you did not personally advocate the position you relayed)

Honest marketing is explaining the value of a product. Marketing can be smoke and mirrors, but to deny its utility is shortsighted.
