This article describes it pretty well: https://caitlinjohnstone.com/2020/08/20/qanon-is-a-fake-decoy-imitation-of-a-healthy-revolutionary-impulse/

"...it's an obvious propaganda construct designed to manufacture support for the status quo among people who otherwise would not support it. It presents itself as an exciting movement where the little guy is finally rising up and throwing off the chains of the tyrannical forces which have been exploiting and oppressing us, yet in reality all it's doing is telling a discontented sector of the population to relax and âoetrust the planâ and put all their faith in the leader of the US government.

And that's exactly what makes QAnon so uniquely toxic. It's not just that it gets people believing false things which confuse and alienate them, it's that it's a fake, decoy imitation of what a healthy revolutionary impulse would look like. It sells people on important truths that they already intuitively know on some level, like the untrustworthiness of the mass media, that the official elected US government aren't really the ones calling the shots, and that we need a great awakening. It takes those vital, truthful, healthy revolutionary impulses, then twists them around into support for the United States president and the agendas of the Republican Party."
