The only way anyone is pulling the data from it is if they tear the BCM out of your dash (it's not easily removed). They had also better hope you were JUST speeding because it only stores the last five seconds.
It's designed to be used in a deadly crash situation where the airbags deploy, so that the insurance company/authorities know what the hell you were doing when you died.
All OBDII vehicles have this, whether you like it or not, and articles like this one do nothing but pray on the uneducated and start mass hysteria among automobile owners.

However, I do agree with the bit about OnStar and I would never, EVER own a vehicle with it. I could go on about OnStar for days but I'll just say this - if any of you have it, once your subscription is over, REMOVE it. Consider OnStar to be OBDII.5 - OBDIII will be something to fear.
