Not the one you're replying to, but I'd generally agree.

If someone wants to post on Peertube, they basically either have to have the time, funding, and know-how to self-host, or arrive with an established audience. Someone with great creative talent does not necessarily want to run an expensive and complicated software project. Someone who has an established audience has very little incentive to jump to federation.

PeerTube is improving slowly. There are now a few instances with open registration, which could mean more fertile ground for good content. We shall see.
