you should know that this in no way requires Apple to jailbreak your phone for you, or lay down its arms in this ongoing fight. Basically, they just can’t sue you for the specific act of breaking their protections, but there’s nothing stopping them from putting those protections in there in the first place, or for suing you for an infringement not covered in this exception — like distributing Apple code in a non-Apple-approved way, or installing illegal or pirated software. Not that any of you jailbreakers would ever do that. What’s more, the DMCA still broadly forbids distributing to the public any “technology, product, service, device, component, or part thereof” that’s primarily designed to break access controls, so Apple can always go after the Dev Team directly
