SAN RAMON, Calif. (AP) — Apple CEO Tim Cook has fired off a series of thinly veiled shots at Facebook and other social media companies. Cook is escalating an online privacy battle pitting the iPhone maker against digital services that depend on tracking people to help sell ads. In a video presentation at a tech conference Thursday, Cook said social networking services’ invasive and misleading tactics could lead to a social catastrophe. His remarks came as Apple prepares to roll out a privacy control in the early spring to prevent iPhone apps from secretly shadowing people. The feature has irked Facebook and other services that depend on such data surveillance to help sell ads.
