According to the lawsuit, Blizzard has required the security devices "in order to have even minimal protection for their sensitive personal, private, and financial data", and that the studio "negligently, deliberately, and/or recklessly" fails to properly safeguard player information.
Some incidents are explicitly noted, including a May incident in which Blizzard acknowledged the hacking of Diablo III, and the August hacking of Battle.net.
Blizzard has made, according to the suit, over $26m from the sale of Authenticators, which cost $6.50 each.
The class action lawsuit is suing for damages, and requesting an injunction from forcing players to have to create Battle.net accounts to play non-MMO titles like Diablo III and Starcraft II. The suit also demands Blizzard be prevented "from tacking on additional, undisclosed costs to ensure security in the form of a post-point-of-sale Authenticator."
