There's basically nothing new here that couldn't have also been said on day one of the App Store in 2008. It's just the standard App Store grievance regurgitated to market their new product.
> Netflix is no longer allowing new customers on iOS to pay for the streaming service directly through an in-app subscription. It’s the latest example of a company with a high-profile, essential mobile app ditching Apple’s payment system to retain more profits for itself and stop handing the iPhone and iPad maker a cut of every subscription activated within the Netflix app. VentureBeat first reported the change, which Netflix confirmed with a short “we no longer support iTunes as a method of payment for new members” statement.
My Netflix's "account" section has nothing but a notice that says "Please go to Netflix on the web to manage your account."
