If Microsoft is selling the Kinect at a loss, then Microsoft will be motivated to keep it locked down to ensure that they can recoup the loss through licensing fees.

So in theory each Kinect sold for hacking is money in MS's pocket.
Given that MS has bought a slew of patents all around this space, they may be playing coy here.
"Please don't hack this... please don't. Oh drats, you figured out a way around our advanced hack-proof system. But what can you do with it? Nothing probably, you surely can't think of some really cool ideas that we haven't... Oh you can give some additional hints to your Roomba from the couch with hand gestures... go on..."
To answer the second question, I know the Dreamcast was sold at a loss. The Nintendo 64 and GameCube were as well, but Nintendo decided that the Wii could be a success if they tried something new instead of trying to be bigger and better.
