Justice Ricardo Villas Bôas Cueva is demanding that the companies detail the criteria used to recommend political posts, distribute electoral advertising and take content down. A study by the Federal University of Rio de Janeiro (UFRJ) found signs of unequal treatment in the election and questions Meta's lack of transparency over the prices it charged, according to Brasil 247.
