And if you sell a product directly... Nobody else gets a cut.Yeah that's true... there is only one choice on iOS.
But all stores take a cut... even if there are multiple stores.
If you sell a product at Best Buy... Best Buy gets a cut.
If you sell a product at Walmart... Walmart gets a cut.
If you sell a product at Target... Target gets a cut.
etc...
Apple makes that impossible on iDevices, and that should not be legal.
