If you use #invidious, be aware that they have received a legal threat from #youtube. FYI, the source code is at https://github.com/iv-org/invidious and at https://gitea.invidious.io/iv-org

I have long suspected that the PeerTube model was better. Make “the main show” independently hosted content, and then if you want, you can bridge to youtube as a side show. I think it is and was totally predictable that lawyer letters would eventually come to Invidious. If you’re not dependent upon accessing videos from YT, you can shut that down if necessary without losing the reason your video site exists.
