There is a long history of legal use of words about what foods are. Like what you are allowed to call 'butter' or 'beer'. There's also the regional names like parmesan and champagne. This looks like its following that established norm.
Yeah but like Hamburger is not from Hamburg though... Maybe you could say Hamburg steak or something but Hamburgers as we know them almost certainly originated in the US.
I don't think accurate food labeling is a bad thing but the contension shouldn't really be around burger to me that's just a pressed shape of cruft but the veggie part. Because Veggie I feel like implies vegatable but like soy-protein or bean mush or impossible burger all could be classified as a veggie burger but like they are very different things and have very different additives. I don't think we are crushing people or industry by trying to accurately label foods though.
I do think that the protectinism to regional foods confusing though. It would be interesting if you could make "feta" elsewhere than in greece for example, but maybe like the originating countries could get a special sigil rather than an exclusively protected food name when its basically indistingusiable to all but a connoisseur.
The butter is my favorite exemple: peanut butter, cacao butter, Vitellaria butter…
"What food are" actually refer to what people use that word for and not necessarily what is the strict scientific definition. I’m sure most knows what’s a "plant burger", although I concede the current law is confusing as you can call an egg or diary many based patty as such.
