That explanation doesn't really work for me. Meat eaters aren't all yee-hawing tailgate BBQ addicts, and vegetarians aren't all paragons of healthy/natural virtue. I know
plenty of people who are happy carnivores, who also enjoy a Beyond or Impossible patty. Usually it's an "every little bit helps" thing, cutting down just a little bit on the health or environmental negatives of meat. Sometimes it's just for variety. Either way, there are people who love meat and also
will touch these products gladly.
The "variety" contingent includes me BTW. I've enjoyed all sorts of vegetarian meat alternatives over the years - old school soy or peanut-based "TVP" in a can back in the 70s, tempeh, bean-based and rice-based and mushroom-based kinds, etc. I make both lentil and potato burgers according to my own recipes. One of the reasons I prefer Beyond to Impossible is that Impossible tastes too much like meat. I can easily tell the difference with Beyond, though, making it less of a direct replacement for beef and more like a different meat to experiment with. That's far more interesting to me.
Unfortunately for Beyond, I think I'm in the minority. Most in-betweeners seem to have settled on Impossible. Consumers want a direct replacement, apparently. Beyond has simply not won in a finite market. There's no need for a Manichean "two types of people" model to explain it.
