Sounds like a contributing factor. But this isn't a normal situation; there's a war going on, and before that there was a huge disruption to global trade due to COVID-19. These aren't the sort of conditions that anyone wants to see continue indefinitely.

"Plant-based meat" already existed before 2015. Then Impossible Burger came up with synthetic heme and thought it would be a game-changer. Long story short, it raised a few eyebrows, but it didn't produce the desired uptake.

I might be missing something, but aside from that, I don't know what the core innovation is supposed to be in the recent products, aside from a big PR push and an economic crisis.
