This is the slippery slope of censorship on display for everyone to see. What panel of certified physicians is YouTube using to identify what information is correct vs. incorrect? I'm pretty sure they don't have any doctors doing this. The ban is a political act and not a scientific one.
Something has to be done. Obvious bullshit is fooling huge chunks of the population and causing huge damage. We have always selected acceptable content and it has usually been a positive. Schools have always picked which info to teach and what to not and that's largely a positive thing.
By definition, 'Obvious bullshit' cannot fool huge chunks of the population. If some bullshit can fool a huge part of the population then it is not obvious to them.
