The EU's highest court has ruled that Facebook-owner Meta must minimise the amount of people's data it uses for personalised advertising.
The Court of Justice for the European Union ruled in favour of privacy campaigner Max Schrems, who complained that Facebook misused his personal data about his sexual orientation to target ads at him.
In complaints first heard by Austrian courts in 2020, Mr Schrems said he was targeted with adverts aimed at gay people despite never sharing information about his sexuality on the platform.
The court today said the data protection law does not unequivocally allow the company to use such data for personalised advertising.
Meta has denied using so-called special category data to personalise adverts.
