I accidentally stumbled across this website:

Don't Mess With Our Chocolate!

Corporate America is at it again; this time they want to relax the standards for defining the product that can be legally sold as "chocolate." They want to cut back on cocoa butter by substituting trans-fat vegetable oils, and also use some kind of non-dairy substitute for the milk in milk chocolate. Yuk!

Sign the petition! Or mail in a letter; whatever they ask for...
