In my opinion, sites like YouTube that rely on user generated content should drop any pretense of being neutral - they aren't and never have been. What they have been doing is dodging responsibility for being the publisher of racist and harmful material.
I'm sure that YouTube would say that they don't play favorites but even if that were true, as we have seen there are organizations all the way up to nation states that are hell-bent on corrupting platforms like YouTube for their own ends. And they don't require much corrupting.
Moderation is key. Sites like Hacker News work only because of strict moderation by humans. Similar sites without such moderation quickly become a haven for trolls and spam. Automatic systems can always be gamed - what is needed is a strong editorial hand.
I don't want YouTube to end - there are thousands of hours of great content. But if it is to survive it needs to make a choice of what kind of site they want to be. Letting itself be anything its users want is turning it into a cesspit.
