I dont think people who would consider a full vegetarian/vegan diet without supplementary products that look like "meat" are the target consumer base for these products. The money is in a consumer base that does not want to fully commit to a certain diet, know that the meat industry is bad for the planet and is unsure on how to go about it.
Personally I'd rather eat highly processed soy beans over parts of a dead animal.
Not that simple, about 5% of the world population has G6PD deficiency and can get sick or die from a diet based on many kind of beans.
I would consider a vegetarian diet, but I can't eat lentils, hummus and beans every day without getting sick (ant my case is quite mild)
