Google provides a method for catering the user experience to the end-user's desires. There is a difference between allowing someone to make a bad UI, and simply telling them they're stupid, so you have made the UI for them (and won't allow any changes).
If you happen to be so inclined as to poorly configure your Android device, that isn't really Google's fault. I for one, like to actually have a choice in the matter. As it happens, I like the usability of my Nexus One very much.
This is such a tired debate anyway. If you aren't intelligent enough to setup a phone, it's not like Google is keeping you from buying an iPhone
