I didn’t watch the video, but it’s YT short, you just swipe like tiktok. The few ways to curate the algorithm is to either swipe away quickly, click on the “not interested” button, downvote, or delete watched shorts from history. If you doesn’t interact with any of this and watch the full length of the video, the algorithm gonna assume you like this kind of content. They also will introduce you content you never watched before to gauge your interest, a lot of times it’s not even related to what you currently watched, and if you didn’t do any curation, they gonna feed you the exact type for some times. I don’t know how they manage the curation but that’s the gist of it from my experience. My feed have 0 politics, mostly cats. I control the feed strictly so i got what i demand.
Divide and conquer, the technique that works so well that British create their empire with it. Single issue voter is so susceptible to it they might as well be the pawn of the powerful.
