There's a sort of circular problem where basically every creator's videos are on YouTube, but many don't replicate their videos to other video platforms. Viewers won't leave in part because other sites lack content, creators won't cross-post because other sites lack viewers.

Some of that would be alleviated if we separated hosting/serving videos from the frontend and indexing, perhaps with a radio-like agreement on what the host gets paid for serving the video to a customer of the frontend. Frontend/index makes money off ads, and then pays some of that back to the host. Creators could in theory be paid by the video hosts, since views make the host money.

Then heavy handed moderation could be a disadvantage then, because they would be lacking content other sites have (though some of that content would be distasteful enough most frontends would ban it).
