The repository was taken down by Winamp, manually. There was no legal requirement to take it down such as with a DMCA or similar. Since GitHub did not have to force-remove it, none of the forks are removed so it's still publicly accessible in one of the countless forks that were made at this time. It is possible, though, at a later time that GitHub may receive a DMCA that will require them to take down all of the forks since the repo contains countless private sources, certs, and other material that was never meant to be released publicly. If you are interested in preserving the source, you should get it sooner than later from one of the many forks before it is potentially taken down legally.
