Okay come on. I believe you saw something credible at some point, but to post "it's common knowledge" two minutes after saying you can't find a source is a really weak argument and doesn't justify "who are you".
Back when the Impossible Burger first came out, there was quite a bit of interest in vegetarian circles. That interest turned sour very quickly as the sustainability of their process was investigated. This was about 2 years ago? Today the vegetarians I know have entirely moved on and the idea of plant based meats is just yet another meat culture noise to be ignored.
