“Spotify says Apple is making it harder for the streaming music company to compete, by blocking a new version of its iPhone app. In a letter sent this week to Apple’s top lawyer, Spotify says Apple is “causing grave harm to Spotify and its customers,” by rejecting an update to Spotify’s iOS app. The letter says Apple turned down a new version of the app while citing “business model rules”
