My brain tingles when I hear "three letter letter agency did X"

But my take on the question: "why is it being pushed by algorithms" is that it is a property of the medium of "algorithmic feeds".

YT, shorts, etc. are a great medium for attention grabbing in a way that is district from TV. Broadcast TV caters to the "average" viewer, ex. Sienfeld, Johnny Carson show. "Algorithmic TV" caters to specialized viewers. Fringe ideas and science, "the truth about X". The crown prince of "algorithmic TV" (IMO of course) is Joe Rogan. For every niche quest he has on, there's many more YT channels on that topic. Weird history, ancient aliens, psychedelics.

So I don't really think the "algorithms" are controlled, rather they "algorithm" elevate weird ideas more than other mediums.

One idea - these days there are many MANY more players using the same strategy - maybe the CIA wants us to be aware of the technique to limit its effectiveness.

Simple enough mechanism in use for normies on YouTube to grasp, vague nationalistic bend, and plenty of people who don’t know makes great YouTube click rates.

I like your comment, though.

Not a direct response to your question; I figure you or others reading this may be interested in the thoughts of the host of The War on Beauty (best found on youtube).
