The Funkwhale music platform is alive and in active development, and they’re working on a feature to filter far-right artists off the network. Some Fediverse self-hosters are divided on letting a third party decide what should be allowed in their library.
Somewhat off topic but I was totally convinced that Funkwhale had died so I ditched my pod and moved to Navidrome, I wasn’t using federation so I wasn’t really the intended audience. I’m glad they are still going though. But personally I’ve had a better experience with Navidrome with Feishin as a player.
