Meta has been fined nearly €800 million by Brussels after regulators accused Facebook’s parent company of stifling competition by “tying” its free Marketplace services with the social network.

The European Commission has ordered Meta to “bring the conduct effectively to an end,” but didn’t specify what actions should be taken. Meta was also hit with a record-breaking $1.3 billion fine by the EU last year for transferring the Facebook data of EU citizens to the US.

European Union regulators hit Facebook parent Meta with a fine of nearly 800 million euros on Thursday for what it calls “abusive practices” involving its Marketplace online classified ads business.
