It turns out WordPress doesn't need to add in-app purchases to its iOS app.
"We believe the issue with the WordPress app has been resolved," Apple said in a statement Saturday. "Since the developer removed the display of their service payment options from the app, it is now a free stand-alone app and does not have to offer in-app purchases. We have informed the developer and apologize for any confusion that we have caused."
Apple said the WordPress app had originally featured a payment-plans section but didn't offer in-app payments, violating App Store rules all developers must follow. Apple gets a 30% commission on in-app payments.
Apple's remarks come after WordPress founding developer Matt Mullenweg tweeted Friday that Apple was going to cut off updates and bug fixes to the open-source software app unless it committed to supporting in-app purchases for WordPress' payment plans.
Mullenweg said WordPress, the open-source website builder used by around 38% of the internet, agreed on a license when it signed up for and stayed in the App Store. "Open source relies on licenses and copyright," he tweeted. "I am a big believer in the sanctity of licenses."
WordPress had agreed to add in-app purchase support within the next 30 days, Mullenweg told CNET in an emailed statement Friday, and was being allowed by Apple to update again.
Mullenweg also tweeted a warning to apps that have similar functionality to WordPress on iOS that don't offer in-app purchases.
"My guess is they will get similar feedback soon so I'd encourage them to start making [in-app purchase] plans," Mullenweg said late Friday.
