I know what you meant: The examples the article cites are biased - most of them stem from one side of the conflicts. The article actually discloses the authors affiliations at the end. But the techniques it shows are not only used by one side and the article never claims that they are. So in itself it is educating the reader to keep an open eye whenever they read a (wikipedia) article. It helps you to avoid biased articles from both sides and that seems to be the authors primary intention.
