I'm having an equally hard time finding the libertarian angle in the top comments to the other threads you referenced.
But whether I personally eat babies or not does not change the problem I have pointed out.
There is a problem that I and others have taken the time to point out, and rest assured if one person points it out, far more don't bother. So whether anyone wishes to address the problem or just downvote the complain itself is not really my concern.
In the end the site is an advertisement for ycombinator and in practice it's really a question of how they want their organization perceived. I had assumed having NY Times articles that point out Russian interference in Swedish politics swiftly whooshed from the front page does not serve that end.
