Is it? There are several GitHub alternatives, many completely free as well, and none of the source was lost unless all the maintainers and contributors also delete their local copies.

The alternatives don't have the mindshare that GitHub has when it comes to open source software. If the community around the game is already weak, moving to another provider will likely weaken it even more. The source won't be gone, but that's only half of what matters.
