YouTube doesn't seem to be interested in hosting any content that isn't manufactured from a giant media corporation or just vapid clickbait entertainment. Just take a look at the trending tab to see what YouTube wants to promote: http://youtube.com/trending

It's worth noting that "Trending" is curated by YouTube itself, and is not an algorithmically determined set of videos.

This is wrong. Trending is based on an actual mathematical formula based on the number of views per hour on the last 48h. Then on top of that you have some filtering who tries to downgrade clickbaity contents. In the US you also have human filtering. Curators can remove a video or ask the Trending algorithm to rate a video before it's normally rated but they can't add a video to an arbitrary position or change the ranking.

Clickbait entertainment is probably over represented but that's also a kind of video who receives a lot of view at the same time which what "Trending" means.
