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.
There’s a couple youtubers that mirror their content on PeerTube. The Giddy Stitcher for example uploads to Makertube.net
