I was curious if mitochondrial cancer could actually happen. Turns out that the situation around mitochondria and cancer is... complicated
I honestly don't understand most of this. I'm pretty sure the original FSTDT post is bullshit — the Nature article is referring to the “role of Mitochondria in cancer”, while the OP is talking about "Mitochondrial cancer," which really don’t sound like the same thing? I honestly can’t find any reputable sources talking about “Mitochondrial cancer” as a thing at all. They’re all just talking about the Mitochondria within a larger cancerous cell.
But, let’s be honest here, we knew it was bullshit when he said that anyone would intentionally engineer a zombie apocalypse. Very wealthy people, who benefit most from organized society, are the last people who would benefit from that.
