You might want to snap up VLC for your chosen iOS device before it’s gone forever. Ré mi Denis-Courmont, one of the principal developers of VLC, explained that VideoLAN (the foundation that supports VLC) is not pleased with how the app is distributed. They have filed a notice of copyright infringement with Apple that may force the removal of the app.
VLC for iOS is developed by a 3rd party developer called Applidium. Apple’s iTunes terms allow VLC to only be installed on 5 devices. This is a form of DRM, and as you may know, VLC is open source and distributed under the GPL. That means Apple’s DRM scheme is unacceptable to the VideoLAN foundation.
Apple has, in the past, simply removed apps that fall into a similar category.
