We know that YouTube has trouble making money with this type of criteria. What do you think is the chance that another company with far less economies of scale will somehow make it work better?

I don't see how YouTube is not giving away half of their ad revenue. Note that even when a video is "unsuitable for advertisers" the creators still get paid by YouTube Red.

A part of YouTube has been captured by activists, and a lot of that policy is warped to their ends. Often, this is political. Often, it's arbitrary abuse of power in service of this or that "Internet slap fight." Either way, it's looks bad to someone who can see the big picture.

Yeah, and this meme is absurd. In what other ad business are advertisers obligated to pay you? Normally when you are trying to sell ads, you have to have a sales team to try to get advertisers to pay you, and it's a constant effort. Creators do not have a right to monetization. If they want monetization, nothing is stopping them from finding their own advertisers and striking their own deals (many creators do exactly this).

And what about Twitch? Plenty of "personality" driven content there.

But if you focus attention to political commentary specifically, then YouTube is clearly the dominant giant. In that context, they are a defacto monopoly.

A giant chunk of uploaded content is never even watched.
