Cheeseburger bill

The US senate is passing the Cheeseburger bill to protect corporations from "frivolous obesity lawsuits".

This legislation confuses me. While on one hand there are nanny state laws coming in to protect kids from obesity, but on the other hand, they are promoting personal responsibility in nutrition. Now while I am all for personal responsibility, I also believe there needs to be some corporate responsibility on behalf of the fast food industry: they need to improve the quality of their food, cut out unnecessary fats and calories, and most importantly, advertise responsibly, don't exploit kids with collectible toys, don't over advertise and don't use discount coupons to increase sales.
