Someone has changed the title of this submission on HN. (The remote web page still has its original title.) And I don't see anyone else complaining about the title on this thread. So I suppose that part of my comment got through.

If you have a feedbackless censorship mechanic like downvoting, one expects people to complain when there's a clear pattern of it being abused; this is exactly what happens when posts in China get censored - people complain. Before my comment, several other very reasonable comments were downvoted to grey as well.
