They accused the social media giant of "targeting advertisements based on the massive and unlawful collection of users’ personal data" in violation of European data protection rules.

The plaintiffs filed suit against Meta on Wednesday before the Paris commercial court, seeking "compensation for the massive economic harm... caused by the unfair business practices of the American giant. Together, they account for 75% of the market and 90% of its growth."

Meta has not yet commented on the lawsuit.
