Why is it false? Either admins intentionally make only specific articles to appear, or they do not, i.e. it happens unintentionally/accidentally. What other options are there? If something happens it is either intentional or not.
Not sure what wrongness has to do with that either.
In the first case it reflects the political preferences of the admin, in the other it reflects the preferences of HN bubble. Either could happen independently of who is wrong and who is right.
