I strongly doubt that. If the product was inferior, you'd maybe see one purchase from someone accidentally buying it, but it wouldn't be sustained.

People want this stuff. We've transitioned our house to vegan milks because, quite frankly, we like them better and they don't have the same awful externalities that milk production has.

We still use some butter and cheese, and some vegan butter/cheese. There are definitely recipes where it doesn't matter which cheese/butter you use, and some where it does.
