There's a difference here. Most people don't make shoes in their kitchen. Most people do produce foods and pick up recipes from regions proximal and distant. It's one of the inherent motivators of travel and commerce for centuries.

Further, Feta, for instance, has existed for hundreds of years. It's no more owned by one person than Greeks themselves at this point. It's spread over the world, in the same way as Parmesan, or other cheeses and foods. The supposition that this is exactly like trademark law is absurd and mechanical.
