Tech giant Apple has issued a heated three-page response to a letter from streaming music company Spotify which had accused that the App Store policies put in place by Apple are ‘anticompetitive.’

Spotify had sent the ‘anticompetitive’ accusation letter to Apple earlier this week, after Apple blocked an update to Spotify’s iOS app, allegedly to thwart any potential competition to its Apple Music service.

In Apple response to Spotify’s ‘anticompetitive’ accusations and to “set the record straight,” Apple's legal head Bruce Sewell has said in the letter addressed to Spotify lawyer Horacio Gutierrez that Apple is disappointed with the public attacks, and is also concerned that exemptions are being sought by Spotify to the App Store rules which are applicable to all app developers.

Detailing the app update issue has been cited by a problem in Spotify’s letter, Sewell has accused Spotify of “resorting to rumors and half-truths” about the Apple App Store service.

In addition, Sewell’s letter to Spotify also drew attention to the fact that Apple has recently announced policy changes to the revenue split model for App Store developers. The policy changes shift the App Store revenue split model 70/30 to 85/15 in favor of the developers, if the subscription for an app is maintained by customers for one full year.
