They turn there because what could be less establishment? The establishment gives its imprimatur to the news media, and they've proven untrustworthy, so the (weak) reasoning goes, why not turn to whatever the establishment condemns? Listen to Alex Jones, Joe Rogan, Sargon of Akkad, Q, the Doomsinger of Alexandria (okay, I made that one up). They don't trust any of it anyway, except a few of the worst Q addicts, but they figure, we know CNN lies and twists, and they hate us, so might as well listen to the liar who's on our side.
Maybe I could have phrased it differently. I really appreciated what you wrote and wanted to add to it, saying that often people don't realize they implicitly trust the sources that they do.
