Maybe Muldoon just has a policy against returning the calls of a full-time anti-Google mouthpiece that is literally funded by DuckDuckGo. It really bugs me how HN acts so skeptically about most topics but falls hook, line, and sinker for every astroturf campaign that comes along.
I too lament HN's complete loss of even the pretense of objectivity when it comes to anything Facebook or Google, but in this case, as long as the accusations are factual, I think there's value in the competition attempting to keep them honest.
