Well, problem one is that gamers have no choice but to accept Blizzard’s word on that. More importantly, if Hoglund is right, Blizzard has a pretty skewed idea of privacy—we can look at your personal info, but if we don’t collect it there’s no invasion? Hardly. We also wonder how Blizzard’s executives would feel if we searched their homes, wallets, and bank accounts and read their letters and emails but didn’t write down anything we found.
More accurately, not remember anything "we" found.
Seriously, why does it matter so much? If it sends personal data, it is obviously a big deal. Until then, though, I am not worried about it.
