EU investigates Facebook over classified advertising data

The investigation is the latest salvo by EU regulators trying to rein in the dominance of big tech companies

European Union and British regulators opened dual antitrust investigations into Facebook on Friday to look into whether the company distorts competition in the classified advertising market by using data it collects from rival services. The EU’s executive commission said that it's also looking at whether the way Facebook embeds its own classified ad service, Marketplace, into the social network gives it an advantage in reaching customers, in violation of EU competition rules. The U.K.’s competition watchdog said in a simultaneous announcement that it launched its own probe to examine whether Facebook's collection and use of data gave it an unfair advantage over competitors providing classified data and online dating services.
