Apple won't allow porn-focused applications in their stores.

Apple won't allow alternate stores on Apple-branded mobile devices, or sideloading.

This is a fundamental disrespect of their customers who have purchased the device. Apple regards their brand image more than allowing their customers to display what they want on the device they own.
