The part of the story that bothers me is not that Apple is locking down the bootloader, or that people are hacking the iPhone to jailbreak or unlock it. The part that bothers me is:
Recent data from mobile advertising firm Pinch Media reveals that it has seen nearly four million jailbroken devices on its ad network, with 38% of those using at least one pirated application.
Why does Pinch Media get such a deep look into the devices that it can tell not only that the phone has been jailbroken, but what apps are on the phone and whether they are pirated or not!? This is way beyond reasonable and, in my mind at least, constitutes a serious privacy breach. If they can see the pirated/not pirated status of all the apps on the phone, how do I know they can't see into the apps - like contact lists, email, etc? Even if they can't, how would you feel about a website that gathered information about all the software (and the licensing) on your computer when you visited?
