Quote:Apple can’t stick to its own rules with the gigantic iOS App Store.

The company recently approved an iPhone camera app that carries a special feature: the ability to snap a photo by pressing the physical Volume button rather than tapping the touchscreen. Oddly enough, about four months ago Apple banned a top-selling iPhone app for including the same “volume-snap” functionality.

In August, Apple rejected the photo app Camera+ when it included a volume-snap feature, because changing the behavior of the iPhone’s external hardware buttons was strictly prohibited.

“Your application cannot be added to the App Store because it uses iPhone volume buttons in a non-standard way, potentially resulting in user confusion,” Apple told Camera+ developer Tap Tap Tap in its August rejection letter. “Changing the behavior of iPhone external hardware buttons is a violation of the iPhone Developer Program License Agreement.”

Following the rejection, Tap Tap Tap hid the volume-snap feature as an Easter egg inside the app and hinted that it could be enabled by visiting a URL in the Safari web browser. That led to Apple slamming the ban hammer. After four months in the penalty box, Camera+ returned last week with the volume-snap feature removed.

So it’s inconsistent that the app Quick Snap got the green light in the App Store, explicitly promoting the volume-snap feature that Apple strictly forbade (see screengrab above).

“Why choose the soft or full screen shutter when you can use VOLUME BUTTON as the hard shutter button on your iPhone?” Quick Snap’s iTunes description reads.

Apple did not immediately respond to a request for comment.

Hosting more than 300,000 apps for the iPhone, iPod Touch and iPad, Apple’s App Store has drawn criticism for some of its rules regulating the content and functionality allowed inside third-party apps. Apple only three months ago published guidelines listing reasons why apps get rejected from the App Store.

But with the case of Camera+, it’s evident that disclosing guidelines hasn’t solved one of the App Store’s major problems: App Store reviewers are not consistent with enforcing the rules, and therefore censorship still seems arbitrary.

I’ve argued in the past that arbitrary censorship in the App Store is detrimental to creative freedom — an issue poised to grow as Apple continues to expand as a major media publisher.
