We originally talked about the problem in late 2011, which made Apple in 2012 even offer a "reward" for a victim of the bug. Two years later, there were still users suffering from it and, finally, Apple acknowledged publicly / officially the problem. It took (too long!), But in November 2014, she launched an online tool designed to unsubscribe from network numbers iMessage.
This did not prevent, however, that Adrienne Moore file a lawsuit against Apple. Not only that, but she asked for justice to evaluate the case as a collective action so that, in case of victory, all owners of iPhones would benefit.
Today, according to BloombergJudge Lucy H. Koh (always she) gave Apple a partial victory claiming that no, the case will not be transformed into collective action. According to her, although the problem was recognized there was insufficient evidence that a whole class of users had been harmed by him. In fact, the flaw only affected those who migrated to another platform (such as Android) without first disabling everything on iOS.
Therefore, the process continues individually for Moore, that is, even if Apple loses the case, the amount that has to be paid in the event should be nothing to worry about.
