That's not what 'fake news' means. It's perfectly clear the piece is speculative and it does not intentionally deceive (even if it turns out to be completely wrong).

The title is "Proof". The url has "proof". Not only is that a misleading click-baitey title, it is also false, because there is no proof.

It's in quotes. It even talks about the quotes. It's obvious from the tone of the thing it's not presented as real proof. And again, "I don't like the title" is not what makes "fake news".

Well this is quite a silly discussion then. If the author is using a title to mean something other than the words in the title in a manner such that the author still protects the veracity of the title, then what is the point of the title? All I can tell it is just a clickbait title.

And then I read the article and see that it is a bunch of speculation and making inferences from puns.

I don't think it's a great article or that great a title. But the fact that it's speculation is completely obvious. And that bit of punctuation is used to change the literal meaning of words, yes. It's just how English works.
