Data without interpretation is irrelevant, and correct numbers can be interpreted wrongly, either on purpose or by mistake.

I’m not saying any of that happened here, only that “are the numbers wrong” is not the only thing that is relevant.

Your parent comment is not complaining about em dashes, they are pointing out the article has a literal “&emdash;” in it.
