Both Google and Apple monetize app discovery by selling advertising spots and such, and both collect revenues from inside apps (be it the mandatory-through-them in-app purchasing systems or advertising). As they are monopolies on their respective platforms, they have no reason to improve your experience, and so they do not care if you find the best app. They care that you find the app that generates them the most revenue, and that's exactly what they're going to do.
