Apple is abusing its control over the iOS App Store to give its own music streaming service an unfair advantage over competitors, Spotify argued in a Wednesday filing with the European Commission.

"Apple has introduced rules to the App Store that purposely limit choice and stifle innovation at the expense of the user experience," writes Spotify founder and CEO Daniel Ek. "After trying unsuccessfully to resolve the issues directly with Apple, we’re now requesting that the EC take action to ensure fair competition."
