European enforcers accused the tech giant of using its popular social network to unfairly advantage its classified-ads business.

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.

The European Commission says Facebook's parent company is undermining its rivals by embedding its classified ads platform within the social network.
