Why do you think the GPL matters? This is MIT licensed and the GPL is incompatible with the app store anyway, so no one can use it. See the removal of VLC.
The issue is with the App Store. Apple can't ban you from using a "private" selector on the Mac, but they can ban you from using a "private" selector on the Mac App Store.
Right, but presumably they want to have one library that can be used both in projects built for the app store and in projects not built for the app store.
Right, and the MIT license is GPL compatible, so people can incorporate this project into GPL projects. But they're considering adding anti-Apple restrictions to their license, which would make it GPL incompatible.
