I feel like it would be best to proxy YouTube, or subscribe to paid indie channels like nebula, but without a user base and without ad revenue or subscription revenue I don’t know how quality content can come to PeerTube. Maybe I’m just missing the content but when I’ve checked it’s all very low quality, just random unedited webcam vblogs mostly.
I haven’t checked it out yet, but the same could be said about the early days of YouTube. Professional cameras weren’t that common for the first years of it.
