I dont get this article "why doesn't Google help consumers find their lost Android phones?"

The OEMs are the ones who are supposed to add this feature to their device. If google add it to their system apps then the OEm can remove it and use their own. They remove everything else even some stock features. Google is just an easy target at this point. Google have an app store for apps. lookout is doing fine. If google create a find your device then lookout would lose users
