I used to contribute to a free iOS app on GitHub that was released under the Mozilla Public License Version 2.0.
Multiple people have since taken the code from that GitHub repository and released apps onto the app store based on that original code. Some of them have just released the app as is with only the name changed. Some have made extensive changes. None of them, that I'm aware of, have released the source to their changes.
Is there any recourse to get them to release their changes?
Has anyone had any success getting Apple to remove apps from their store, from developers who similarly ignore the terms of the original code's license?
