"textured wheat protein" - no idea what it, but it sounds disgusting, and very highly processed. I'd presume it also contains gluten?
"potato protein" - again, it sounds like something highly processed.
"natural flavors" - it doesn't specify exactly what they are, so I don't even know what I'm eating - I don't like it.
"leghemoglobin" - you mentioned what this is, but otherwise it sounds like a lab-produced chemical.
"yeast extract" - makes me think of marmite, which is one of the most revolting substances on earth! Aside from that, I think of the smell of yeast; I... don't think I want to eat that.
"konjac gum" - never heard of it.
"xanthan gum" - I think it's some kind of thickening agent?
"soy protein isolate" - no idea what this is. The wheat and potato proteins don't have "isolate" in their names, so I assume this is even more highly processed. For some reason it makes me think of processes like "hydrogenation" - ways we mess around with foods to make them as cheap as possible, sometimes with negative health consequences.
"vitamin E..." - makes me think the raw ingredients on their own are so unhealthy that they had to add a few crushed multivitamins.
Overall: it sounds highly processed and devoid of nutrition. blech!

And if you find yeast "revolting", I take it you don't like bread or beer either?
I know it wasn't your point, but as an aside: isn't the "used" yeast slurry removed from most commercially produced beer? (depending on the style, obv)
Each of the ingredients bar "natural flavors" (which usually means a proprietary spice blend or msg) can be found with a simple Google search - as someone else said, konjac is an Asian vegetable, textured wheat protein has been a staple of vegan cooking for decades and can be bought in any health food shop, and so on.
> isn't the "used" yeast slurry removed
From beer, partially. From bread, no.
You may be familiar with these ingredients, but that doesn't mean anyone who isn't used to highly processed food is "wrong" for not knowing what they even are.
Here's the ingredients list for the impossible burger:
Water, textured wheat protein, coconut oil, potato protein, natural flavors, 2% or less of leghemoglobin (soy), yeast extract, salt, konjac gum, xanthan gum, soy protein isolate, vitamin E, vitamin C, thiamine (vitamin B1), zinc, niacin, vitamin B6, riboflavin (vitamin B2), and vitamin B12.
The only thing unusual is leghemoglobin, which is fermented soy protein.
