Nobody can downvote articles on HN. However, if an article is off-topic or otherwise violates site guidelines, you can flag it. I don't think this article should be flagged however, since it's a rare glimpse into how the Chinese Communist Party tries to influence world opinion (although I doubt many could be convinced that China is a democracy).

Off topic? I just read an article about Sesame Street, and followed it up with an article about tornados, followed by a video of "Planes I see from my front yard." I'm not sure what topic HN really falls under.

It's discussed in the first couple of paragraphs of the HN Guidelines:
