Entirely one-sided discussion (to put it kindly), with dissenters finding their comments invisible. For as good as the discussion around here usually is, there are some topics that even HN cannot have an open discussion on, and that happens to be one of them.

Try an experiment: Argue in a thread that Facebook/Google/etc. are anything less than mustache-twirling-villian levels of evil, or that the people that work for those companies sometimes make actual human mistakes.

Arguing against the mainstream position can even get your comment flagged. Doing it a few times (even about unrelated topics) will get your account banned for being "incendiary". HN is an echo chamber. But that's not surprising, all Internet communities are an echo chamber to some point.

On HN I see lot of hand-waving away of ethics and a lot of defence of straightforward greed.
