Google and Google users, are implicitly granting governments the permission
to collect that data, and to snoop on that data, and to use that data for whatever reason Google and governments deem necessary.
People already know about Google's tactics for collecting and datamining and snooping in on that user data, but, most people don't mind or don't bother to complain, which is, in a sense, explicitly granting Google permission to use that data for whatever purposes Google sees fit.
When government requests people's personal information from Google, and people don't raise a stink about it, then, it's another explicit permit granted to Google to hand over that information. If people were to stand up to Google and to the invasion of privacy being perpetrated by government, then, chances are that, we might get more government officials to listen to us and might get some laws and regulations to stop that snooping and invasion of privacy.
