If limiting the spread of 'misinformation' is their intended goal, it seems like they would have a bigger impact by just toning down their algorithmic recommendations. Leave the videos up and available to search, and stop doing hyper-optimized recommendations designed to increase 'engagement'. Of course, that would lose them advertising money, which is probably why they didn't go that route.
