After being here long enough, you'll just notice that certain companies and agendas get pushed pretty hard, when in reality they are using a lot of accounts to manipulate the discussion and emotion once you start looking at the comment history. It is no different than Reddit or Twitter.
It's a POPULAR online forum, which is why people care. If tomorrow no one gave a crap about HN but HN mods still wanted people, they'd have to welcome more discussion like all the other nobody forums.
