I'm just going to note you agree that these examples are contrived yet nevertheless want to debate them, apparently to performatively exhibit your appreciation for the values open-mindedness and free speech.

That's a not a constructive use of anybody's time. It's a frivolous distraction. Youtube is doing what they can to save lives by stopping misinformation in the face of a global pandemic. If you're more interested in turning this into a navel gazing exercise, I'd say you're suffering from a serious lack of perspective.
