That was just an example, and that is why I started saying that it will be interesting to study flagging of articles. I have been around HN since 2009 and the flagging has been increasing in the last year. Most probably because of international and national conflicts.
I browse new pretty frequently, I think what you're seeing is more nation state actors or just newbies flooding HN than any change in policy. The stuff getting flagged has always gotten flagged, there's just more of it. Any accusations of political bias feel pretty misguided unless you want to present some specific examples.
