Cheese is being referenced because it's a natural extension of "You can't call it X if it's not the way we used to do X". If Texas wants to limit the definition of meat, then logically they should be limiting the definition of cheese, milk, and even salt, for that matter.
Without that, it looks less like a matter of evenhanded regulatory enforcement or consumer protection, and more like a legislature beholden to a corporation.
I brought it up because the GP said "tofu is not bean cheese" when that's almost exactly what tofu means.
