All advertising is misleading in a sense, the question is where to draw the line: the legal complaint (http://www.courthousenews.com/2011/02/02/Nutella.pdf) states that the moms were duped because they saw TV commercials that showed moms feeding Nutella to their healthy families. Although I think the ""An example of a tasty yet balanced breakfast." label should be removed from Nuteall jars (which'll be done, http://commonlaw.findlaw.com/2012/05/nutella-lawsuit-company...) I don't the millions of dollars awarded (I misstated this, actually it was $3.06M) makes sense, but then I'm no lawyer.
BTW, you can go to this site (https://nutellaclassactionsettlement.com/FrequentlyAskedQues...) and claim up to $20 if you've bought Nutella, no receipts asked (until the allocated $2.5M runs out).
