Funkwhale is the fedi alternative for music. You should go post your feature list onto their forum.

I just took a look at faircamp, it seems nice too.

Dogmazic.net is also a music platform (centralised) made with ampache.

Mots people do care about privacy, but most people see more pressing issues that goes first. It’s hard to care about something intangible when it’s hard to have a roof over its head, or to pay the bills.

Also musicians won’t hesitate to put their audience at risk. They doesn’t care about what they’re asking their audience, because they ‘feel’ like they have no choice. Which is objectively wrong.

And musicians are often ignorant about copyright laws, so how can they protect their audience if the don’t know how to defend them self?
