The Justice Department requested the case be vacated after obtaining access to the iPhone used by one of the San Bernardino shooters with help from a third party.
Here is Apple's full statement:
From the beginning, we objected to the FBI's demand that Apple build a backdoor into the iPhone because we believed it was wrong and would set a dangerous precedent. As a result of the government's dismissal, neither of these occurred. This case should never have been brought.
We will continue to help law enforcement with their investigations, as we have done all along, and we will continue to increase the security of our products as the threats and attacks on our data become more frequent and more sophisticated.
Apple believes deeply that people in the United States and around the world deserve data protection, security and privacy. Sacrificing one for the other only puts people and countries at greater risk.
This case raised issues which deserve a national conversation about our civil liberties, and our collective security and privacy. Apple remains committed to participating in that discussion.
While the Justice Department has ended this particular matter, it's unclear if it will continue pressing Apple to unlock iPhones in other cases.
