You understand that this whole discussion started with somebody saying "wouldn't it be cool if these labels were solely based on quality instead of location"?
Yes, we all know that it's a brand name, and they can do whatever they want with it. We are talking about how that maybe shouldn't be the case. Do you understand that? What value do you bring to the discussion by saying "but they're allowed to!!!1!1!"?
If the location has an effect on quality, it is measurable purely by quality without taking location into account. If you need to know the location because it's not measurable, it shouldn't be taken into account.
