That's the key, when you said "many" consumers would consider past products incomplete: it's quite subjective whether to call a product complete or incomplete. They would never admit to wrongdoing because there'd always be some way for them to argue otherwise.

As I mention in my other follow-up comment here: http://news.ycombinator.com/item?id=4586212, the difference in this case is that the product is objectively incomplete: the data itself is measurably bad.
