Companies running subscription-based apps privately complain that Apple is acting anticompetitively. It has had similar problems in the ebook market, where a federal judge recently upheld a ruling that it had conspired with publishers to inflate prices. Apple and Spotify declined to comment for this story.
The prohibition on developers telling consumers how to find products at lower prices is ripe for legal challenge, says Tim Wu, a professor at Columbia Law School and a prominent critic of anticompetitive business practices in the tech industry.
"I think Apple is getting close to the line, if it hasn't crossed it, in its dealings with Spotify," he says.
Apple's charge is ostensibly a service fee that developers pay to use its platform. But it doesn't take a cut of purchases in markets where it doesn't compete. GrubHub, for instance, allows users to purchase food directly through its apps without splitting the pie with Apple. United Airlines doesn't share revenue when it sells tickets through its iPhone app.
Last May, Daniel Ek, Spotify's chief executive officer, said that he was concerned about a company like Apple abusing its market position to cut off competition, but he also said he didn't see it happening yet.
