Selon les plaignants, le géant du commerce en ligne aurait surfacturé ses clients annonceurs de plus de 20 milliards de dollars depuis 2019, grâce à un mécanisme d’enchères publicitaires qu’ils jugent trompeur.

Federal regulators and 22 states allege that the tech giant made billions by manipulating how much brands and sellers paid for ads on its platform.

The lawsuit covers a seven-year window of time and involves over 20 state attorney generals.
