It's possible that you're neglecting something essential in the factors relevant to content provision. Torrents allow decentralization, and make it unnecessary for the site to store and stream the content, meaning the servers necessary to create the site are tiny and inexpensive compared to a service that must store and stream the content from their site.
For this reason Bitchute offers potential unmatched by the competitors. This is not to say that more traditional service models are impractical, but that they are orders of magnitude more expensive, and any site that hosts and streams content centrally is prone to censorship.
Torrents, by their decentralized nature, are inherently immune to censorship.
