>A service just hosting videos (without recommending some of them) would be just fine.
It might be "just fine" in an abstract principle kind of way. However, reality would not support such a site because of human preferences.
The problem is that viewers want recommendations (both in search results and followup related videos) and content creators want to be promoted (to get views and ad revenue or sponsorships).
This means a video site with recommendations will outcompete a "dumb storage" video site where surfers must know the url for each video they want to play.
Perhaps it means that editorializing as a service is necessarily a business that needs to be kept separate from the hosting of videos - sort of like the older style of curated link lists that directed users to particularly interesting content existing beside the DNS service that stored an unbiased record of all content.
