Cook referred to the case two years ago when the Federal Bureau of Investigation asked Apple for access to the iPhone of the San Bernardino shooter, Syed Farook. The technology giant refused to help the FBI, citing issues of data privacy. Cook called the request "chilling."
The debate sparked a wide discussion over government interference in a technology company's data. Law enforcement argued the data would help solve terrorist cases. Technology companies rebutted, stating that without encryption, iPhone users will become easier victims to hackers.
Cook also criticized the data privacy practices of Facebook in the same interview.
