Both the NYT and CNN are running prominent anti-4chan, anti-conspiracy stories right now. They didn't have this type of coverage about conspiracy theories when Las Vegas, Pulse Nightclub, and other previous mass shootings, so what changed? Q happened.
I strongly suspect that all of this is laying the groundwork for when Q hits the mainstream. They introduce the idea of /pol/ spreading "fake news" and "conspiracy theories" now, so that when people see the legit Q screenshots, they're already trained to dismiss it as fake news. These article could also be launching points for bigger anti-Q articles in the future. Remember, Q warned us of a massive anti-conspiracy push. I think this might be the beginning of it.
