The WHO hasn't changed its views due to "new science", the shifts have all been for political reasons, as was sometimes admitted by their own staff. Additionally this notion that it's ok for "experts" to set policies and claim science as justification then totally change them on a dime largely voids the whole original justification. It implies their original "science" was totally wrong in ways they couldn't detect and thus they presented it with absolute confidence, then they discovered they had badly screwed up but never admitted to it or investigated what went wrong.

In the end, science is respected because it claims to reveal universal truths about nature. If those truths are constantly being announced to be obsolete such that the new truths aren't mere refinements but totally different, what use is science?

As for authoritarianism, preventing people disagreeing with a global authority is a pure example of it, no? YouTube shouldn't even bother trying to figure out the truth here, they aren't able to do so. Just let people thrash it out amongst themselves.
