Apple has been lauded this week as crusaders for smartphone privacy, after the federal government compelled the company to install a backdoor into its own software (which Apple promptly denounced).
Despite its refusal, Apple has already divulged a potential trove of private information from the San Bernardino shooter's phone, which includes the iCloud backups and all associated iCloud data. This is standard practice for Apple, which as a (normally) law-abiding company provides law enforcement with all data relevant to investigations, even extracting information from phones multiple times in the past.
Tim Cook confirmed this protocol in his now-infamous missive "A Message To Our Customers."
"When the FBI has requested data that's in our possession, we have provided it. Apple complies with valid subpoenas and search warrants, as we have in the San Bernardino case," Cook wrote in the letter.
