This message has been posted on their discord server yesterday, currently the app is being worked on and has no definitive ETA. We probably have to use other forks until that. I don’t know whether I can share the discord server’s link so not sharing that until a mod gives heads up.
GitHub didn’t do anything. This isn’t because the code was taken down (it’s still there, as are all the forks that are also perfectly legal); it’s because the maintainers decided it wasn’t worth putting up with big pocketed harassment to keep doing it.
Based on some other article I saw on this yesterday, my understanding was that GitHub was likely going to take them down for the BS DMCAs they were receiving, but maybe I misunderstood what I was reading.
GitHub (and everyone else) is required to follow the process laid out DMCA takedown requests. The uploader just has to submit a counterclaim, and they can put it back unless they actually go to court and file a lawsuit.
The whole process is dictated by the DMCA.
