Apple isn't alone.
The tech giant is dominating the headlines in a standoff over whether to help the FBI access the locked, encrypted iPhone of one of the San Bernardino terrorists, NBC News reported.
But this case is just one example of the broader tension that has erupted between tech companies and the Justice Department across a range of national security and criminal issues.
For example, Microsoft's CEO Satya Nadella is fighting the DOJ in a drug-trafficking case. The government is trying to force Microsoft to turn over emails stored in data centers in Ireland as part of the investigation.
Twitter CEO Jack Dorsey is also going head-to-head with the department. The company says it is being prohibited from reporting on the scope of surveillance of Twitter users by the U.S. government. Twitter argues that it entitled to do so under the First Amendment, and seeks to publish a full and complete report on transparency.
