Ann Reardon (not Reed, as I wrote originally), from "How to cook that" did a video on it. Basically Youtube rewards interactions, and a dislike is an interaction. Her main evidence was a video by pewdiepie where he asks everyone who views it to dislike it. It is one of his most viewed videos, at least around that time, and by far the most disliked. Sadly Ann Reardon names her videos after what she cooks or debunks, and not her critiques on the algorithm (she has quite a few really good one) I'd appreciate if someone knows the link.
