You are most likely being downvoted for muddling the object(s) of your criticism. The Google navigation app runs on Android but so do other navigation apps. You've made a set error in your logic confusing the subset for the superset. A fair criticism would be to try different apps, weigh them out and present a measured response based on that analysis or specify that you're criticizing Google's app specifically and constraining the boundaries to that app and not the platform it runs on.
