I think it was an old hippie thing, arguments from being closer to nature (rather than merely less harmful) were powerful back then. Today? The comparisons between wild and domestic crops are broadly circulated in the press and memes, premium mock meats are pushed by companies purporting to be high tech operations, there's no way you'd be spearing wild tofu swimming up the river because it doesn't exist.
Haven't seen any of that either. Not saying no one says that but I have trouble believing that it is a persistent enough meme to be attributed so broadly to any social movements.
