I think google do sloppy shit whenever the "sloppiness" suits them. Take app permissions in the play store as an example; you mean to say google are so concerned by me installing unvetted apps that to do so, I have to click some check box somewhere in the settings, YET do not allow me to set app permissions on an app by app basis? That is downright sloppy, only it isn't really sloppiness, it's a state of affairs that one way or another suits their needs.
Coz think about it: even after they've seen plenty of apps asking for permissions that are none of their business, apps that they've approved seeing as they're on the app store, they still don't change their permissions policy. I call that intentional slopiness.
