Matt Asay, of Read Write, predicts Android will be the preferred home for open source developers in the future. According to data from Black Duck software, "new Android-related mobile open-source projects outstripped open source iOS projects by a factor of four in 2012, growing by more than 96% each year since 2007. New iOS project growth, on the other hand, was just 32% from 2011 to 2012."
Developers have historically favoured Apple's iOS due to its superior developer tools and monetization. This shift toward Android should be concerning to Apple, as it might suggest open-source developers are beginning to view Android as a better platform for launching new innovative apps.
