And many people who has called Kindle CS for tech problems have probably experienced the fact that Amazon can access your Kindle over the internet as long as the Wifi/3G is on - this is a good thing because it means they can resolve many technical problems without the customer needing to send it in for repair/replacement.
You can always turn off the wifi/3G on your device (if it comes enabled). My Sony is not wireless.
I agree, though, that I find the loss of privacy disturbing and creepy, and big corporations are taking more and more liberties with regard to tracking consumer behavior. I would even go so far as to say that many big corporations are going further than people realize in tracking behaviors and invading the privacy of those they employ.
