nobody said "this isn't relevant to humans"

The article is written in such a way that you think it is about human cells until you get fairly far into it.

Well, it’s how mitochondria in cells in worms cooperate. We already know cells cooperate through many channels and some channels we understand quite well. This is truly only about worms right now. Obviously generalizing to other animals will be important next steps. But the title and text of the article implies a much more general understanding than we actually have. It’s not to diminish the results in the least. But science isn’t served by claiming progress we haven’t made, it makes it harder to fund the next step by building an assumption of nonexistent progress.
