We finally have a statement from the former Firefish owner/lead Developer. It seems that the Firefish site and Gitlab is given to one of the maintainers. Still, I kind of consider it EOL as the new person in charge isn't a programmer. It's pretty much doesn't change anything unless a new lead developer decides to take on the project. I do wish Kainoa the best in his future endeavors.
There are other options, such as Sharkey, IceShrimp and Catodon. However, IceShrimp is doing a rewrite in C#, so it's basically going to be it's own thing, which might be interesting to try, but not something I would use outside of personal use. Same with Catodon, which might use IceShrimp's C# rewrite.
I have a lot of trust in Sharkey's team in making sure something like this doesn't happen while making it community driven. Taking the Glitch-soc approach like with Mastodon will make Sharkey a more viable option since it’s just Misskey with extra features, some making it to mainline Misskey like with some things from Glitch-Soc making it to vanilla Mastodon.
