The Gnu Public License decrees that software distributed under its terms may not have its usage be restricted in any other way. Apple’s terms of service for the App Store apply limits to the apps distributed through it, which by its very nature conflicts with the Gnu Public License according to the Free Software Foundation.
Rémi Denis-Courmont, a developer who is part of the VideoLAN group that produces the VLC software for a number of platforms, had notified Apple of this conflict in late October, predicting that Apple would simply remove the app from the App Store rather than amend its own terms of service to avoid conflict with the Gnu Public License. He announced the removal of VLC Media Player from the App Store on Saturday after he was notified by an Apple attorney.
While VLC Media Player is no longer available in the App Store, users who downloaded the app before it was removed can technically continue to use it. Without the ability to update the app, however, it may cease to work in the future if changes are made to iOS that make it incompatible.
