I'm guessing the plan is to cast a wide net, then hope that you can dredge up some incriminating or morally ambiguous quotes during discovery. When you have a company of 100,000+ people, there's probably some "haha we're killing the competition" in there, which you can then use to prop up the case.
And then either use that to win the trial, or force Apple into settling.
