I don't. I don't know where you live, but unless it's on a farm, branded foods are obviously not a US-only phenomenon. Anything even remotely processed will be based on proprietary recipes. Regular meat burgers and sausages are just as "proprietary" as Beyond Meat ones, let alone foods like candy bars or snacks. Do you think Snickers bars are not proprietary?

Nevermind all of the specialty foods across the globe. Products made from basic ingredients and labeled to sell are everywhere. What exactly are you referring to?
