You can call it censorship or not, but it's not a good look either way.
No, you're interpreting things here in a specific way.
It could be that users didn't think it belonged on HN because it was politics, which is often frowned upon. It could be that they thought there was a problem with the article itself.
In any case, even if it was totally the community choosing to not want to see this news (which I doubt), it wasn't a deliberate action by the people running the site, which does make a difference (otherwise that would've been the original accusation).
