I agree with you that SV in titles has largely become linkbait but in this case it seems reasonably accurate.

We're pretty careful to take linkbait out of titles on HN, but beyond the gratuitous "Inside" I didn't see a lot. I suppose we could s/dark side/side/ as well.

So, 4 prominent people who attended the party (including one woman who stayed until 5AM), have attached their personal names to statements saying this article's claims are fantastical. Combined with the fact that nearly all the claims are anonymously sourced, I don't see how you could claim it seems reasonably accurate, unless you are experiencing confirmation bias (which is what I think happened here).
