Sure, but improvement to the education system won't come into effect for decades, and in the short term, real people are dying from anti-vaxx and anti-mask misinformation. I know 2020 has been wild, but let's not forget the huge surge in Measle deaths, something that was mostly solved beforehand. Blocking certain content now literally saves people's lives.
For sure, but I think it's important not to lose sight of the fact that YouTube is merely dealing with the symptoms of a much broader societal problem. We can't truly fix the issue until we address the root cause. Everything else is whack-a-mole.
Again, why not both? This is a short term solution, while we work in parallel in improving the education system. Youtube itself can be a great source of education if you promote scientific videos over trashy conspiracy videos.
