It's all true lol. However if you wanted to spy on someone would you rather have a camera that's pointed right at the main location for most people showing a wide swath of landscape or a camera that most of the time is off or in someones pocket? I don't know about you but my phone doesn't have a forward camera, and my tablet well..is off most the time laying in a pile. As for laptops, sure, but they are already snooping on those and have been for years. Those are also mobile, a completely different issue for them to deal with. The whole point is console cameras in general stay put, always connected, and have technology built into them to work remotely (I mean you don't have to physically touch them to turn them on - not NSA backdoors).
If you look at the usefulness, the Xbox camera (or PS4 if you want to include it) is an easier route.
What I do find unbelievable is the people here trying to dismiss it as conspiracy and farce. That is truly funny. Those are the attitudes that have made it possible for everything that has already happened to happen. How many people no longer use Skype? I'm guessing not many stopped after it was revealed that MS was working with the government.
