The Free Software Foundation (FSF) is not happy with Apple. They say that Apple's App Store distribution of an iPhone port of GNU Go "is not in compliance with the GNU GP." They say that Apple's Terms of Service violate the terms of the GNU GPL (General Public License). According to the GNU terms, through distributing GNU software, the code must also be freely shared and can be copied and modified by the user.
Ars reports that the issue first came up when the FSF found that the developers of the iPhone version of the software weren't in compliance with the requirements of GPLv2, which state that anything created as a derivative of code under a derivative code must also be licensed under the GPL.
The FSF has already contacted Apple regarding the issue. The FSF has also said that they have contacted developers of such software since they say, "legally, both parties have the responsibility to comply with the GPL."
