It was a flag for
meta.stackexchange.com/questions/332229/… to add the featured tag, as it is an official response to a featured question that is getting hidden due to downvotes. Others have suggested that it get flagged for the featured flag for that reason. I'd understand if it was declined because staff want to hide it so less people are aware of what's happening, but I can't imagine why it would be declined for "pointing out inaccuracies".
