Daniel Ek, CEO of Spotify:
It’s why, after careful consideration, Spotify has filed a complaint against Apple with the European Commission (EC), the regulatory body responsible for keeping competition fair and nondiscriminatory.
Good. After reading through his post and their website - especially if it all is true - they have quite a good case. I've been complaining, for years, about iOS's anti-competitive policies. I am glad someone is finally going to try to get Apple to loosen its grip.
While Spotify's main objection is the tax Apple puts on apps and services in the Store my main objection would be not allowing me, the customer, to choose my own browser, mail client, music player, etc. I really hope this is the last straw and many more complaints somehow make their way to Apple's legal department.
