The FTC and the US Department of Justice are reportedly debating which of the two agencies will launch an inquiry into Apple’s new policy of requiring software developers for Apple devices (including the iPhone and iPad) to use only Apple’s programming tools. Advocates favoring regulatory intervention argue that by forcing programmers to choose between developing Apple-exclusive applications and applications that can be used by other devices, Apple is hampering competition by forcing developers to focus on a single format. Apple responds that it has no obligation to make it easier for developers to port iPhone applications to other devices. An article on the potential investigation can be found here.
