Earlier quoted context omitted.
Beyond Meat aren't unique, there are dozens of brands offering the same product. Tens of millions of people eat these type of products. Any (or most) burger-serving restaurant in Europe will have a Beyond Meat or equivalent on the menu. They're not always advertised as vegan (because of preparation and extras) but these fake burgers are very popular, for many reasons.
Fake? In my part of the world, a burger is a type of sandwhich, and the definition doesn't require meat. So it's a burger whether it contains beef, fish, chicken, a vegan patty, a large slice of tomato, or whatever.
Given all sandwiches, what in your part of the world makes a sandwich a burger? I think for many of us it's a ground patty. If said patty isn't meat, yes we might say that is fake as in an imitation of the original. It's not a negative thing.
