Many people trust this "word of mouth" way of telling stories, but for those who know rhetorics this pattern should raise a warning. (it is not my intention to accuse, just doing some rhetoric deconstruction) The "so the teardown is correct" part is backwards. Calling the billionaire ceo by his first name tries to create an aura of personal knowledge. At the core it is an argumentum ab auctoritate. Honestly this is worse than "amazon said so" because it is veiled.
