They're the General (Mills) in charge here

General Mills in charge: If you like a product by General Mills on Facebook, it may prevent you from being able to sue the company!  

The NEW YORK TIMES went in depth on why 'liking' a product voids the right to sue the product's maker.. I have always thought about this myself on Facebook.. that is why I don’t ‘like’ things of any market value. I frankly typically don’t ‘like’ much on Facebook at all.
