Facebook joins Google under the European Commission's microscope for the way it handles data.
"These investigations concern the way data is gathered, processed, used and monetised including for advertising purposes," said a spokesperson. The crux of the issue is to find out whether Facebook restricts data access to third-party companies, and what that's all about.
Earlier this year, Google was fined £1.2 billion for its aggressive advertising, which was dubbed an abuse of its power by EC Competition commissioner Margrethe Vestager: "Google has cemented its dominance in online search adverts and shielded itself from competitive pressure by imposing anti-competitive contractual restrictions on third-party websites," she said at the time.
"This is illegal under EU antitrust rules. The misconduct lasted over 10 years and denied other companies the possibility to compete on the merits and to innovate – and consumers the benefits of competition."
