New questions arise. Has data gone to Chinese servers? Have back doors been created for Chinese hacking? And obviously, users were not told their data would be used in this way. Yet Zuckerberg told Congress in April that users have “complete control” over how their data is shared.
FB says the data was merely used to optimise FB software on the devices. Mark Warner, top Democrat on Senate Intelligence Committee: “I look forward to learning more about how Facebook ensured that information about their users was not sent to Chinese servers.”
