Facebook denies it shared user data without consent. That's where a Trump-connected political consulting firm used data derived from as many as 87 million Facebook profiles in order to sway election results. So far there's no evidence that phone and tablet makers used Facebook data improperly, in sharp contrast to Cambridge Analytica consultants. User would log into their Facebook accounts, allowing the phone software to pull in data from Facebook itself. Apple said it used data pulled in from Facebook to let people post photos and other items on Facebook without opening the Facebook app.
