Throughout 2015, prosecutors in the United States argued for the U.S. government to be able to compel decryption of iPhone contents. After the 2015 San Bernardino attack, the FBI recovered an iPhone 5C that was issued to one of the shooters by his employer, and iCloud backups of that phone from a month and a half before the shooting. (The shooters had destroyed their personal phones.) The U.S. government attempted to obtain a court order under the All Writs Act compelling Apple to produce an IPSW file that would allow investigators to brute force the device passcode. Tim Cook responded on the company's website, outlining a need for encryption, arguing that if they produce a backdoor for one device, it would inevitably be used to compromise the privacy of other iPhone users. On February 19, Apple communicated to journalists that the password for the Apple ID for the iPhone had been changed within a day of the government obtaining it, preventing Apple from producing a workaround that would only target older devices.
