I don't think the problem is that you see an advertisement for a KitKat and then you want one. It's more subtle than that, and something more than the familiarity the article talk about. What advertisement does is to change the associated concept in our minds. At some level I know that it's only a piece of unhealthy sweet with plenty of chemical preservatives, too much sugar and, probably, zero chocolate, but what I really perceive it's another totally different thing: It's a KitKat! It's cute! It's not just a sweet, it's a new category in my mind. What I, personally, find specially immoral is the advertisement for children.
