Exactly. I don’t why it’s always surprising to people that court battles are fought over legal definitions. That’s how legal definitions are made.
Vegetables are not anything that is not a fruit. Tomatos are both, as are cucumbers. When you say “technically a fruit is blah blah blah”, it says nothing about whether something is vegetable. The definition is from a different domain. The definition of vegetable seems to have to due with human digestion. The botanical definition of fruit doesn’t care about the existence of humans. Vegetables are culinary and to some extent cultural. “Fruit” also has a culinary meaning, but its not technical in that domain. There is no way to “technically” distinguish between fruit and vegetables as “vegetable” isn’t technically botanically defined.
