As a content creator, once you've recorded and edited your content, you have to solve for a few kinds of things:<p>1) hosting, content delivery, authentication and access control, styling and UI, etc.
2) discoverability, which requires things like a search engine, recommendation engine, a community/social network, links, etc.
3) some degree of independence, and the freedom to decide what content to show, what content to monetize, etc. free from whatever agenda/motives a company like YouTube/Alphabet might have.<p>One way to look at it is that PeerTube starts to make (1) a lot more accessible without something like YouTube. (2) is where YouTube shines, but is possible via existing structures in the Internet if you're just using PeerTube (plus PeerTube has some sort of federation, though I haven't looked into it much). (3) is where PeerTube shines.<p>There doesn't have to be one answer for the entire market. YouTube is probably better for smaller creators looking to build their audience and be discovered, but once you reach a sufficient size, and don't need to rely on the YouTube recommendation engine for people to find you, something that offers greater independence and self-determination would seem desirable. Of course, I'm only talking about tendencies, a very small content creator may have a strong desire for independence, and a a very large content creator may be perfectly fine coloring inside whatever lines YouTube draws.
