Isn't the more prescient issue the use of lab grade plasma (or whatever is used in petri dishes and stuff) which comes from sheep blood? Wouldn't that be the location of any actual vegan/vegetarian backlash to fake meat?

Or does fake meat not use this material in its production? Maybe it is only used in researching fake meat?

I would guess they're only used to research fake meat. As in, to understand the chemicals and nutrients that make up actual meat and give meats their properties. An example I suppose would be to understand the chemicals and reactions involved when cooking meats e.g. how meat browns when cooked[0] and then synthesise these chemicals from plant matter[1].

Do you have any sources for this claim? Why would they use petri dishes to grow GMO yeast?
