Still puts the onus on the wrong party. The videos in question had 10's of thousands of views but were produced in such large quantity that the sum of all videos was in the millions of views. By law of large numbers even if you educate 95% of the population how to notice when something's not right, an exploiter like this can still just keep getting views from the other 5%. And the channel in question was in Vietnam, very likely views were coming from all parts of the world. It's not like adding critical thinking to US school curriculum could have stopped this anyway EDIT: Rereading your comment I realize you were talking about how this gets shared at all and the algorithm that's used to make these videos recommended. My guess is that the channel had a couple dozen or hundred subscribers, and they maybe did some advertising on r/aww or something similar. I don't think it would be hard to get the numbers they were getting even if YouTube wasn't recommending these videos to anyone at all
