If you really want to, pretty much any feature could be seen as against consumer choice. "If I don't want it I shouldn't have to pay for it."
MS has made Kinect an integral part of the Xbone system. It may not be physically built into the machine (because that would be against consumer choice, forcing people to place their consoles in awkward and risky positions to be able to use the Kinect) but it's still part of the console. It's part of the Xbone, and it wouldn't make sense for MS to not include it.
To me the HDD is more anti-choice (and it's still stretching it), because you're forced to pay for a 500GB drive that you may have to switch out rather soon if you're planning on getting a lot of digital content. Why can't you buy a system without HDD and just get the drive you need from the start?
And don't get me started on proprietary storage...
