How Facebook’s data sharing went from feature to flaw
Gold mine of user-supplied info is behind a growing controversy over how that info was used
LOS ANGELES— With each comment, like and share, users provide Facebook with a personal window into their lives.
The result of that voluntary behaviour? Advertisers looking to finely target their pitches can glean someone’s hobbies, what they like to eat and even what makes them happy or sad — propelling Facebook’s ad revenue to $40 billion (U.S.) last year.
This trove of rich information is now at the centre of a rapidly growing controversy involving one of U.S. President Trump’s campaign consultants, Cambridge Analytica, which reportedly took the advertising playbook and exploited it in a bid to influence swing voters.
Former employees accuse the firm, owned by the conservative billionaire Robert Mercer and previously headed by Trump’s former chief strategist Steve Bannon, of taking advantage of ill-gotten data belonging to millions of unwitting Facebook users. News of the breach was met with calls over the weekend for stricter scrutiny of the company. Democratic Sen. Amy Klobuchar demanded that Mark Zuckerberg, Facebook’s chief executive, appear before the Senate judiciary committee.
Maura Healey, attorney general for Massachusetts, said her office was launching an investigation. And the head of a British parliamentary inquiry into fake news called on Facebook to testify before his panel again, this time with Zuckerberg.
The accusations raise tough questions about Facebook’s ability to protect user information at a time when it’s already embroiled in a scandal over Russian meddling during the 2016 U.S. presidential campaign and under pressure to adhere to new European Union privacy rules. They also highlight the power and breadth of the data Facebook holds over its two billion users. Whether used to sway voters or sell more detergent, the information harvested by the world’s biggest social network is proving to be both vital and exploitable regardless of who’s wielding it.
“The data set assembled on people by Facebook is unrivalled,” said Scott Galloway, a professor of marketing at New York University Stern School of Business and author of The Four: The Hidden DNA of Amazon, Apple, Facebook and Google. “The bad news is, people are discovering this can be used as a weapon. The worse news is that people are learning how to detonate it.”
The controversy began late Friday when Facebook’s vice-president and deputy general counsel, Paul Grewal, announced in a blog post that the social network was suspending Strategic Communication Laboratories and its affiliate, Cambridge Analytica.
Facebook said the companies failed to delete user data they had acquired in 2015 in violation of the platform’s rules. The data was supplied by a University of Cambridge psychology professor, Aleksandr Kogan, who built an app that was supposed to collect details on Facebook users for academic research. Kogan was not supposed to pass that information to a third party for commercial purposes under Facebook guidelines.
Facebook said the data collection was contained to 270,000 people who downloaded Kogan’s app as well as “limited information” about their friends.
But a whistleblower and other reported sources contend the scope of the data collection was significantly larger. Christopher Wylie, a departed cofounder of Cambridge Analytica, said Kogan harvested data from 50 million Facebook users without their permission, largely by mining friends of the people who downloaded his app.
The allegations were first reported by the New York Times and the British newspaper the Observer, whose stories about the breach were pre-empted hours earlier by Facebook’s announcement of the suspensions.
Wylie, who described Cambridge Analytica as a weapon designed to wage a culture war in the U.S., said Facebook wasn’t particularly adamant about censuring his former company. He said the only effort made by the social network was sending a letter in August 2016 demanding that the data Kogan supplied be destroyed. He said Facebook never verified whether the data had been deleted.
Facebook, which also suspended Wylie, did not respond to a request for comment.
As recently as last month, Cambridge Analytica told a British parliamentary hearing that it never had or used Facebook data. But in a statement Saturday, Cambridge Analytica admitted receiving user information from Kogan and then deleting it after learning it violated Facebook’s rules. The firm added it never used any of the data for Trump’s 2016 campaign when it was hired as a consultant.
According to a story in the Guardian, the British newspaper, Kogan maintains everything he did was legal and says he had a “close working relationship” with Facebook.
Cambridge Analytica reportedly needed Facebook’s data for its so-called psychographic profiling, which combines data collected online to glean a better understanding of voters’ personalities in order to tailor ads to them.
In many ways, it’s not unlike what Facebook can do for advertisers and a growing number of political campaigns willing to pay and play by Facebook’s rules.
By micro-targeting users down to what charities they donate to, what device they play video games on and where they stand on the political spectrum, Facebook says its reach is expertly tailored to its clients’ needs.
