Facebook confirmed this week that it struck data partnerships with at least four Chinese electronics firms, including Huawei, a telecommunications-equipment maker that U.S. officials view as a potential tool for state-sponsored spying. WSJ: The four partnerships are among the roughly 60 that Facebook struck with device manufacturers starting in 2007 so they could recreate the Facebook service on their devices, a Facebook spokeswoman said. As of Tuesday, more than half of those partnerships have been wound down, the spokeswoman added. The social-media company said it plans to wind down its data-sharing partnership with Huawei by the end of the week. It isn't clear when Facebook will end partnerships with the three other companies: Lenovo, the world's largest personal-computer maker; Oppo, a smartphone maker; and Chinese electronics conglomerate TCL.
