Emacs and Magit
If it were to be accepted into Emacs itself that would only be the beginning of the story.Right now Magit is hosted on Github and anyone can contribute by just sending a pull request.If it were part of Emacs you'd need to use the FSF's collaboration tools which have a higher barrier of entry, and if you're a first-time contributor with a non-trivial contribution you're going to have to wait days/weeks as your copyright assignment papers make their way over snail-mail.I've contributed several (trivial) patches to Magit, zero to Emacs itself, and would likely have contributed zero to Magit if it had been an FSF project to begin with.I think the FSF has gotten their priorities seriously wrong. The package is already licensed under the GPLv3, they're wanting to subject everyone to a more onerous contribution process to guard against the edge case of someone ripping off one specific Emacs package and the FSF not being in a position to have standing in court if they wanted to sue them.
