NBC News report revealed that Facebook used user data to leverage relationships with other companies. The social media giant rewarded some firms with extended user data access after they spent money advertising on its platform; as well as withholding user data from other companies that posed a competitive threat to the social media firm. Researchers stressed that top tech firms need to re-evaluate the meaning of responsibly collecting and sharing data, and that user consent needs to be highlighted and prioritized in the future. However, they also said that users need to take steps themselves to safeguard their data.
