edit to tone down the accusatory tone of my previous comment. In retrospect, the post was likely derailed due to a subthread discussion that appears to have been flagged.
Interesting in the sense that similar things happen all the time- stories get posted and either get no traction or else somebody starts a boisterous subthread with flags and downvotes that results in the HN algo downgrading "arguing".
FWiW it's currently #2 on https://hckrnews.com/ .. but that's chronology of submissions with votes, unweighted by comment numbers / arguments.
