Chobani ad campaign draws Lanham Act suits

The NYT has a story here.  Interestingly, the campaign is similar to some others I've seen condemned by the NAD and even the FTC in the context of "green" claims, by focusing on the use of chlorine etc. in producing some of the ingredients in competitors' yogurt.  If the chemicals aren't present in the yogurt itself, or aren't present in amounts significant enough to affect health, then Chobani could have a problem.
