Obviously it's true and not a surprise to anyone familiar with the history. But no one is asking more complex questions: why is it being pushed by algorithms and networks ultimately controlled by the same powers? Is it a "limited hangout"? Well poisoning? What does the "CIA" gain from revealing a sliver of its past activities and discrediting (both directly and by insinuation) a large number of radical artists and thinkers?
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.
I like your comment, though.
