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 looked around in five years, but there was some interesting tech tinkering stuff on that diode instance. I’m assume people reuploading their own YouTube channels doesn’t count, but there were some quality ones there even back then.
