@Coffee Peertube is pretty good, but what it lacks most is not features, but ease of deployment. I - being a bit of a geek, run my own Peertube server, but my artistic and musical friends still put their works onto YouTube. It needs to be comparable in effort to setting up a YouTube Studio.
Packaging for Debian or Fedora would help, as most could afford a Freedombox or Raspberry Pi, but these also need to be easy for a musician to set up as a server at home.
