It set off the flamewar detector. See https://news.ycombinator.com/item?id=25921688.

Someone replied on that other thread that it's more than likely users flagging it.

The cynic in me thinks that there's quite a few "negative pr" posts that name corporations or specific companies that end up getting flagged but that could be a coincidence (biased by the recent media/pr firms that astroturf so I could be wrong).

I believe "Ask HN" type threads tend to get routed downstream faster, while links are held on the homepage longer. (That one did not have an "Ask HN" tag, but was just a question posted.)

Speculation on the other thread is too many people have flagged the other post.

In which case the next logical question is why have users been flagging it? It does not appear to violate any HN guidelines.
