This looks like the CEO misquoting the policy. I linked to the actual policy. Where does it say what you claim?
> "Now any content that disputes the existence or transmission of Covid-19, as described by the WHO [World Health Organization] and local health authorities is in violation of YouTube policies."
This is in violation for spreading harmful medical misinformation, not for contradicting the WHO, which (once again) is not prohibited by YouTube policy.
> There's a convenient feature called search on HN or any other websites. I think you might want to use it.
If you had used that feature, you might have come across https://news.ycombinator.com/item?id=22963070
I suggest you learn how to read critically instead of blindly believing anything you read on the Internet.
One is an actual policy that the employees follow. The other is just a quote taken out of context. The interview wasn't about launching a new policy. Instead, the CEO mentioned what YouTube was already doing in passing in a broad-ranging interview and did so loosely.
It's really not that hard to understand. You're acting like the Black Knight in Monty Python and the Holy Grail.
