Is Apple ’s glide slope to how goods are bought and sold on iOS gimmick convert ? That seemed to be the instance Tuesday , as a developer accused Apple of freeze off its app in a money catch .

The foiled developer in question is Sony , which went public ( an deed Apple warns developer against ) over the rejection of its Reader for iPhone app , a front - end to Sony ’s vitamin E - book entrepot .

According to a storypublished on Tuesdayby theNew York Times , Apple rejected Sony ’s app and requested that it be modified to take vantage of Apple ’s in - app purchase system . Sony alsopublished a statementsaying it has “ reached an blind alley ” with Apple and is now “ exploring other boulevard to wreak the Reader experience to Apple fluid devices . ” ( presumptively this mean a web - based reading organization . )

What makes Sony ’s case different from that of other e - book apps like Amazon ’s Kindle app , which has long been on the Io ? From theNew York Timesreport it seemed that Sony may have offer an interface for purchasing books right within its app , which has always been a no - no — Apple ’s guidelines make it readable that buying stuff inside an appmustbe execute using Apple ’s in - app leverage arrangement , which uses your Apple ID and linked credit visiting card . This is why , when you prove to buy a book from the Amazon Kindle app , you are instead sent to Amazon.com via the Safari vane internet browser .

But it deform out that Sony may have been a canary in the proverbial coal mine . Numerous media organizations , includingMacworld , contacted Apple and received a gossip from Apple interpreter Trudy Muller . Here ’s Muller ’s assertion :

We have not changed our developer terms or guideline . We are now requiring that if an app offers client the ability to buy book outside of the app , that the same choice is also available to customers from within the app with in - app leverage .

The argument seems a bit confounding , but what it seems to be saying is that although terminal figure and guidelines have n’t exchange , Apple is now apply them other than . Basically , Apple is mandate that any Word of God app that offers the power to corrupt material outside the app should also offer the power to grease one’s palms clobber inside the app , using Apple ’s arrangement . ( It ’s an interesting alteration , since antecedently Apple ’s policy on the matter has been to preclude app developers from using Apple ’s commerce organization to ply any sort of productoutsidethe app experience . )

This is irrefutably a modification in policy for Apple , and the ramifications are staggering even if you limit the cathode-ray oscilloscope to rule book . It mean that Amazon , Barnes and Noble , and other booksellers will take to offer an in - app purchase option for all their Holy Writ , and give Apple a cut of the takings .

If this were implemented today , it would be a catastrophe — there ’s not even elbow room in Apple ’s system for all the volume in Amazon ’s catalog . And while a 30 percent reduce on all sales in the App Store seems sane , that same 30 percent cut for content that ’s neither tracked nor service by Apple seems eminent . It would be impossible for Amazon or Barnes and Noble to maintain exist book prices while also cutting Apple in for 30 percent .

It ’s unclear if Apple would also mandate that damage remain consistent inside and exterior of the in - app leverage system ; if that authorisation survive , it ’s difficult to see how Amazon could keep its front on iOS . If it did n’t subsist , you ’d get to see all those in - app purchase prices be much higher than the ones available on the outside . And given the existence of Apple ’s own iBooks intersection , the hypothesis of government investigating for anti - competitive conduct seems with child even before you cast aside the possibility of mandated pricing policies on the heap .

Then there ’s the larger question : what about products other than books?Macworld’sdigital - replica edition is usable on the gratis Zinio app , which follow Amazon ’s take - it - to - the - internet glide slope ; will Zinio be required to offer in - app purchase for all its cartridge holder ? Will Netflix be need to offer subscriptions in its own iOS apps , in add-on to via its Website ? Will the eBay app be necessitate to offer a Buy It Now release via in - app leverage ? ( bazaar point : some apps , such as most of the comic - book of account reading apps , have been using in - app purchase all along , and would n’t be affected . In fact , Apple ’s new insurance policy might make content bought in those apps more portable than it is today . )

Another shoe to drop?

Deep intimation . Let ’s not get too hysterical just yet . give that Sony has forced this issue into public view , it ’s entirely potential that there ’s more to this story that Apple just is n’t unforced to reveal yet . It could come as presently as tomorrowat the launching of Rupert Murdoch ’s The Daily iPad newspaper publisher , in fact .

What would make this entire policy go down smoother with app developer is if Apple separated its celebrated 30 percent cut on app sales from its less - known 30 percent reduce on in - app content sale . When Apple announced the App store in 2008 , the company suggested the 30 pct cut was think to “ pay for running the store . ” But app downloads — which are served by Apple and require an approval operation — are much more resourcefulness intensive than in - app purchase . If Apple were to change the damage of in - app content purchases to be more akin to a credit - bill processing fee , publisher would have less to squawk about .

Money away , this decision by Apple has the potency to be quite consumer friendly . In - app purchase are soft and familiar . recruit your Apple password before making a purchase has become second nature to iPhone , iPad , and iTunes users . make to go to a Website to infix in your recognition card or lumber in using a dissimilar substance abuser ID guide longer and is less commodious . Presumably content vendors would sell more stuff if they were capable to standardise on Apple ’s in - app system — the question is , would it be enough to make up for the cut Apple takes ?

For a couple of years now , Apple has been boasting about how many millions of iTunes IDs are colligate to credit board . late grumble paint a picture that the troupe isseeking to expand the footmark of its financial services , too . It ’s exonerated that Apple is tired of seeing companies make money on content wait on to iOS twist without using its system or sheer it in for a piece of the action . The current 30 - percent cut of all substance purchases would seem to be an impediment to catch partners to comprehend Apple ’s system ; on the other hand , Apple ’s the ostiary to its platform and if other companies do n’t want to play ball with Apple , they ’ll be on the outside looking in .

What take place next calculate on Apple ’s reckoning about how much leverage it has with those who need to be role player on the App Store platform . Change is undoubtedly derive in full term of how users corrupt stuff in iOS apps . Exactly how much alteration will have a lot to do with whether Apple is in the operation of changing its term , or if the fellowship is content to keep things as they are and see what happens next .
