Megacorp decides to purchase KFC.

As part of due diligence, they want to know what the secret recipe is. After all, you'd hate to find out one of the special herbs and spices is cocaine or arsenic. This is fine because MegaCorp signed an NDA.

MegaCorp breaks off the deal. Their chefs decide that they can make their own chicken. After all it's not hard to combine these nine herbs and spices.

The chefs only have this knowledge because you revealed your trade secrets under the protection of an NDA. They're not white box reverse engineering the recipe.
