I would have guessed this was in a very strong sense a linguistic issue. Does a composition "veggie burger" present an oxymoron, thus forcing the consuner to either interpret the composition as being one or the other? Or does the adjective merely make a more specific case? A compiled list of similar compositions would in my opinion help the counter argument.

The line of reasoning of the agricultural lobby about "confused consumers" feels to me like an insult to public's intelligence.

Their arguments about protecting farmers is valid and needs to be considered.

I interpret it as an adjective; there are already a variety of alternative burgers such as chicken or turkey burgers. They're typically meat, but I guess I've never assumed they had to be; just that most plant-based sandwiches are closer to other things. Interestingly, salmon in patty form is usually referred to as a salmon patty even after being cooked (at least around me).

I don't find it at all confusing. A veggie burger is a patty made of veggies, just like a turkey burger is a patty made of turkey. The only case where I think it might be confusing is if the patty is made out of something that could plausibly also be blended into the meat of a regular burger. If the box said "jalapeno burger" and inside was veggie burgers with jalapenos in them, I'd feel mislead.
