This is true, but it is an important topic so here is another angle to consider:
YouTube doesn't have any tools to sift right from wrong that we don't already have, and their censors are probably only marginally more intelligent than average.
They are going to get stuff really wrong from time to time, and eventually are going to censor important information - if they haven't already, it is hard to tell.
Case in point, censors generally aren't bought in to hit stuff that is obviously wrong. Everyone knows that sort of content is garbage and only watches it for a laugh (think flat earthers). They are coming in for stuff where the available evidence makes it difficult to tell what is true or not (eg, ivermectin). They're going to make some horrible mistakes playing at that game, because by nature of what they are targeting, some of it is going to be factual content.
