It depends who your application is for. You obviously think building an application is about maximizing your profit, and your users are just a means to achieve that. If you were approaching your application from a “what’s best for my users” angle you might make different choices.
If you are running a business with limited funding (which is most businesses), then your primary need is to seek profit in a world where profit is often never achieved at all. Otherwise, your business ceases to exist, along with your app. Sometimes that does mean emphasis on strong design, which I’d argue means delivering a great experience to your users rather than a native or non-native design choice. Other times, you’re serving a demographic that doesn’t care so much about that, and your focus is on functionality above all.
