The relationship between Apple and Spotify could be headed for a rough patch after a report about emails from Spotify instructing its users not to buy their subscriptions through Apple's app store. It's a dispute that perfectly illustrates Apple's awkward relationship with digital media companies, which rely on its app store as a major source of distribution even as they compete with Apple's own media businesses.
The emails from Spotify, posted on the Verge yesterday, explained to users that they pay US$13 ($19) when they purchase subscriptions through the Apple app store, compared with US$10 on Spotify's website. The price difference is because Apple takes a 30 per cent cut of subscriptions purchased through its app store. The emails explained how to cancel the app store subscriptions and sign up on the Spotify website.
Apple doesn't encourage this kind of thing. The company forbids any buttons or links within apps that could allow people to buy things externally that they would otherwise purchase through the app.
While its guidelines forbidding this practice aren't clear, it's likely that Spotify's iOS app would be rejected if it had included its email as a page within its app.
The same restrictions don't apply for Android.
