If I buy physical goods, I have an expectation that I completely own it and can do with it whatever I want, and can share my experience completely with others.

What Sony is trying to say is that when you buy a PS3 you are sort of renting it, and they still own what you can and can't do with it. Perhaps because they are selling it at a loss so they can make money when you buy games. I think that in this case they should NOT sell the device to consumers but lease/rent it, because that is the agreement they are really looking for.
