I find it hard to believe that app stores like Apple iTunes and Google Play are not consider monopolies by the government. For each phone OS (Android, iOS, Windows) there really is only one available option and it is always the only one installed on the phone.
While most of the services these app stores provides are helpful (apps are vetted for inappropriate behaviors, app reviews) the companies have complete control over where the apps are listed and they charge a huge fee of 30% for all purchases made through these apps.
I know some companies have tried to bypass the app store by offering HTML 5 versions of their apps through the phones browsers but since these app stores are the go to place for "apps" none of them succeeded. The companies always reverted back to using the app store so there software can be found by their customers.
Now I don't mind a company making a profit by offering a service but taking 30% from each purchase has to be price gouging. If I were an app developer (which I am not) I would be pretty angry about this.
I figured some governments would be jumping all over this like they did back when Microsoft's Internet Explorer was considered a monopoly.
