I wouldn't describe this as fake news at all, but I'd say that one person's view on a video they have watched isn't comparable to that dossier, which was (apparently) compiled from numerous in-person visits and interviews. Not to mention, reporting on the dossier always clarified that it was not verified, while this opinion piece is making broader conclusions.

I agree with you broadly, though. To me, fake news has absolutely no mooring in reality whatsoever and is pure clickbait - usually without political motive beyond getting angry people to click.
