alt Hacker NewsI 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?
Bread, cheese etc have names that says what it is that is unrelated to brand. That is the normal way for most products, a minority of products in the grocery stores I visit are brand only, most things you can get essentially the same from another brand. Exception would be sodas and candy and such, but that is a tiny fraction of what people buy.
Its like when I go to a pizza place I can get the same pizzas regardless where I go even though they are all independent, the recipe for most things people eat in the world are not secrets, its stuff anyone can make and sell.
