Personally what found even worse is the attitude of an arrogant Firefox developer (Marco), who came to /r/firefox and just outright dismissed any and all concerns, than closed all bugzilla tickets about it and just left subreddit (at least for several days). It feels like some "genius" manager who brute forced his "brilliant" idea on the team.
