The research conducted by Consumer Reports indicates that, on average, an astonishing 2,230 companies actively share data about each user with the social networking app. Consumer Reports joined forces with The Markup to recruit 709 volunteers willing to share their Facebook data archives. This allowed the organizations to analyze “server-to-server” tracking, uncovering how many companies were sharing user data with Facebook by transferring personal data from their servers to Meta’s servers. Consumer Reports also pointed out that participants were probably more privacy-conscious, technically inclined, and likely members of Consumer Reports, indicating a potential bias in the sample.
