I think this is being overblown.
It appears to me that Apple and/or Gruber style articles just happen to trigger the flame war dector that HN has implemented which demotes posts (to keep HN more balanced in what content is promoted & civil).
Nothing malicious. And it’s hard to argue HN isn’t better off with the flame war dector, than not having it at all.

Also, why didn’t Gruber just contact dang to ask at hn@ycombinator.com
As someone in the press, it seems Gruber should know better than to create flame bait articles if he didn’t bother to even ask the mods.
