I wouldn't call it dark pattern but rather an anti-pattern or just a plain-old mistake/oversight. Dark pattern implies the website gains something by misleading the user. In this case, the guy actually loses hits/viewer to the main website he is talking about. So it is more of a usability oversight than usability insidiousness.
