Unfortunately for Blizzard and Activision there are legal issues with privacy and the internet. If you haven't been breathing for a long time some of the recent upbringings of this are the NSA and Google being forced to permit information withdrawal. Sure, the actual legal terms are rather blurred as technology advances laws have to be written to accommodate them, but Blizzard was under fire by the media when the warden was introduced and they have further claimed to back down. I highly doubt they don't abide by their statements or they could face a class action lawsuit from an amass of nerds, as well as media uproar. "Unauthorized Access" is definitely illegal, and will get the afflicting program labeled as spyware and persecuted to legal action under the various computer crime acts. I have a few more links but they're just as vague, but at least I have a source.
