The BBC and Ars Technica, amongst other sources, have reported regarding the FBI's latest filing in the FBI vs. Apple case regarding government-mandated unlocking of the phone owned by the San Bernadino terrorist.
The US Government's reply to Apple (which was linked to by Ars Technica) makes the claim (page 34, line 6) that:
For example, according to Apple’s own data, China demanded information from Apple regarding over 4,000 iPhones in the first half of 2015, and Apple produced data 74% of the time.
It makes the citation
Wilkison Decl. Ex. 8 at 3. for that claim, which was not included as part of the document.
Did Apple's data show that they helped the Chinese government unlock thousands of iPhones?
