Cambridge Analytica whistleblower Christopher Wylie warns that Facebook targeting threatens free speech
Christopher Wylie, the whistleblower who outed Cambridge Analytica for improperly accessing millions of Facebook users’ personal information, warned that unchecked data collection and targeting on social media threaten Web users’ privacy — and the healthy functioning of democracy. Wylie, who worked at the consultancy before it assisted President Donald Trump’s 2016 campaign, pointed to Facebook’s tools that allow political candidates, advertisers and others to reach discrete categories of Americans online.
