It’s unsurprising that Apple would put its users in this predicament; they’ve made no secret of the fact that they intend to control what people do on their products with an iron fist. Whether they stop you from doing certain tasks by banning VoIP apps, or limit people’s speech by selectively blocking political commentary, Apple sees to it that App Store apps serve Apple’s interests first, Apple’s business partners’ interests second, and yours a distant third.
We have a different idea. We believe that people should be allowed to use their computers however they like, whether the devices are shaped like laptops, cell phones, or tablets. The GPL was designed to ensure that everyone has that right, and the free software community has been writing software for twenty-five years now to make those rights a practical reality.
