You are only partially correct in your analysis. Yes, controlling the platform can lead to a better user experience. But how does banning browser engines lead to better app quality? It doesn't. If you look at the history of app store restrictions, you'll find that any app that provides an open platform or programming environment has been banned. That is because it takes the control out of apple's hands. It's a power grab.

Some restrictions do. Some restrictions have economic benefits for Apple.

This one has both.
