No, "Fake News" is a term coined to allow a blanket dismissal of anything made public that political leaders don't want to be heard. There certainly can be factual falsehoods in news, and it is worth evaluating how well news organizations are reporting facts... but "Fake News" was the opening salvo before following up with stating that fact-checking is insulting.
Let us not validate the concept by embracing the term. It is a weasel word for people who want to promote their own flavor of misinformation.
As far as Wikipedia goes, this shows a loophole that needs to be closed. I'm amused by it - I can also understand why others are not.
