First off, the article in question was an editorial, not reporting.

Second, the issue with the Henry Harpending reference isn’t that he’s a forever morally stained as a person. His career is built on bullshit theories, and he doesn’t get to wipe the slate clean with every article he publishes. It’s perfectly reasonable to redact a reference to his work if you have reason to believe his conclusions are tainted by ulterior motives.
