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.
Setup is also huge pain and it has compatibility issues with clients that use the subsonic API. Every step of the way something I needed from it had issues. I gave up running one funkwhale instance for multiple users and instead spun up 4 Navidrome instances. Not only was it easier and more stable it also uses less resources than one funkwhale setup.
As much as I love the idea of funkwhale it’s just so far away from usable.
