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.
Its open source, the admins can turn it off by reverting the patch. The person who coded it has the final say on what their software does in an open source world if you dont like it you are welcome to fork it. The fork should still be able to connect to the network and interact as it did before.
