Related: The EU is super anal about names and designations. Remember when they tried to ban plant based meat patties from being called "hamburgers?" Even though the word hamburger is literally German for "of/from Hamburg," in reference to its claimed birthplace, and nothing about the word implies that it has meat in it (English speakers sometimes think it's referencing ham). This is 100% not to protect consumers or the environment but to protect businesses. If they gave a shit about who they claim to protect they would be going the complete other way, promoting and normalizing plant based alternatives to animal products.

Same with plant based milks IIRC. It's not even enough for them that they're called "soy milk" or "oat milk" or something even though the usage of the word in that way has been in the common vernacular for ages. Only nipple juice shall be bestowed the title of milk in these fair kingdoms! Seriously, do they think consumers can't tell the difference when it's already spelled out for them on the packaging and plant based food producers actively promote the plant based aspect as a selling point? They think people are too dumb to read the huge bold text that literally say "plant based" or "vegan" right next to the product noun?
