|This is a surveillance device that lets you make calls.|
Your calling/texting/Facebook is of little value - that's why the marketing companies get that data.
The intelligence gatherers want to know who you're around and what you're talking about. So when a group (N < 1) of targeted devices are in proximity, the mic/camera are activated and 'samples' taken. Those samples are analyzed for keywords, flagged for human review if necessary.
Ever wonder why so many politicos and celebrities used Blackberry? (it wasn't a surveillance net like Android/IOS.)
Why did the NSA ask for/get months of phone data? Chinese hacking.
China wants access to the Google surveillance platform(s). If China can hack their way in, they too can spy on influential Americans.
Probable scenario: China wants to promote its wine products. It targets the Northern California wine region by undermining political support for the wine growers. This is accomplished by using the Android/IOS systems to track influential people (nodes) in the political network and interrupting or introducing conversation elements (i.e., critical messages do not relay, or conversely, messages introduced or edited by China (the "Inherent Trust1" problem.)
For scaled analysis systems to identify this activity, the NSA needs to develop 'signatures.' This is why they needs tons of phone data. Ironic that a gov't agency is coming under fire for doing its job (arguably very well, too.)
Obama's role in this is simply to be a distraction. While you're busy being angry at him or venting spittle about the NSA, Google and Apple are quietly downloading your family's photos, listening to what you talk about after sex (with both your spouse AND your affairs!), gathering data about your TV viewing2, and most importantly, which clusters you associate with.
This is not the future - it is the now. The present. What lies ahead is the revealing of this system and your eventual coming to terms with it.
1 - you have been taught to trust 'your' device in that when it tells you a message has been received from your friend, you believe it 100%.
2 - YouTube has an media ID system that tracks copyright infringement on the website. Android uses the same system to identify what you're watching when it samples mic audio from your phone. Most accurate market research, ever.
