For reporters covering Facebook, getting the real story has only become harder since the release of the “The Facebook Files” in 2021. The Wall Street Journal series, based on documents provided by whistleblower Frances Haugen, exposed the inner workings of the company now known as Meta, from its lax rules for VIPs to internal research on Instagram’s impact on teens. Jeff Horwitz, a reporter for The Wall Street Journal, writes about the challenge of covering the company in his new book “Broken Code: Inside Facebook and the Fight to Expose Its Harmful Secrets.” Marketplace’s Lily Jamali spoke with Horwitz about how he’s covered Facebook and Meta and how Meta’s platforms have changed over the years.
