Spotify has taken another swipe at Apple.

The audio giant, along with other companies including Deezer, publisher Schibsted and Basecamp, has written to Margrethe Vestager, evp of A Europe fit for The Digital Age European Commission, requesting “swift and decisive actions” against Apple’s alleged anticompetitive practices in Europe, which the companies claim prevent them from growing. 

The companies wrote that Apple’s “excessive commission” to app developers and restrictions to access user data create a barrier for its consumers and make it difficult for companies to generate revenue.
