According to the Financial Times (a subscription is required to read the article), Apple has hired Sandy Parakilas, a critic of privacy practices at Facebook, to serve as a product manager on its privacy team. His job will be to work with teams throughout Apple to ensure new products guard privacy and minimize data collection.
Parakilas was an operations manager for Facebook between 2011 and 2012. He spoke publicly last year about how covert data harvesting by third-party developers was routine, just as Facebook was under scrutiny for failing to police developer use of its platform.
He also gave evidence to the UK and EU parliaments hearing about the scandal. He told Business Insider at the time: "I have no intention of stopping until the company is doing all it needs to do to protect our elections.”
