I cannot understand why people who were fine with the Kinect on the 360 are not fine with the Kinect on the One, for privacy reasons.
In both cases a microphone is attached to a console running closed sourced software that could conceivably switch on the microphone and upload data without your knowledge.
The only difference with the One is that data from the microphone will be used at all times by an offline process (not uploaded), and analysed by some software for the sake of generic commands. This doesn't help the NSA listen in on you. They could already do this even if the microphone wasn't always listening for voice commands.
There is no more reason to be worried about the One listening to you than a 360 or your mobile phone or your laptop or any other device running closed source software.... and by that, I mean that all of them are privacy concerns and it is terrifying that so many people are complacent about this. 'Nothing to fear, nothing to hide.' Even if you trust our current government with intimate knowledge and complete surveillance of all of its citizens, does that mean you trust all conceivable future governments? You realise that an untrustworthy future government would have potentially decades of data collected under previous administrations? Are you seriously happy to have this kind of relationship with the state despite the great danger it puts our society in?
Oh sorry, I meant to say 'herp derp they can have pics of my dick anytime'
