Fair enough; but that is a side effect, and a rather obvious feature given that Amazon had already proven the value and importance of user ratings (even if they are largely fake now). Also, I wonder how the rating system was working for the people who were victims of assault or crime by an Uber driver in some countries... There was little question that the existing taxi system was bad, but Uber didn't roll in to right the wrongs, it rolled in to "disrupt" and take the market.
