It looks like they also prioritize health/medical YouTubers, even if they're not doctors if they're big (i.e. with the verified checkmark). Given that this seems to be the case, I think this is a pretty reasonable approach to soft moderating. I don't want YouTube to purely filter out potential health remedies because layperson experimentation is sometimes how medical "truths" of the day advance (e.g. doctors used to love spouting nonsense about how "diet doesn't affect acne" and with n=1, laypersons pushed back enough that new research showed that to not be the case). I think giving the floor to "credible" YouTubers and institutions is a fair balance.
