A former boss of mine used to talk about how he found economics interesting, because unlike telling someone not do something and watching them ignore you, with economics you can change the rules of the game so they don't want to play any more. "Fake news" is just another manifestation of the same old "Thirteen cat facts you won't believe" and even "One simple tricks" we've been seeing for years. It's economically profitable to make large amounts of people look at your site. Until that stops being the case, all of the parasitic crap we see on the web will continue to grow. It will grow bigger and faster, too, as more people get connected to the web, and don't know what's "true" and what's not. I have no concluding remark to this observation, other than get used to it, unless you're a decision maker at Adwords, in which case pull your finger out and realise you hold the position of power to stop this.
