Former Meta engineer resumes testimony in landmark trial over social media’s harm to young users

A former Facebook engineering director and vocal critic of Meta Platforms who has accused the company of ignoring internal research on the harm its platforms can cause children and teens will continue his testimony on Wednesday in a trial that could remake Instagram and Facebook.

Arturo Bejar, who worked at Meta from 2009 to 2015 before returning to the company as an independent contractor from 2019 to 2021, is the first witness in a landmark trial over claims brought by a coalition of states accusing the company of designing its ‌platforms to addict young ⁠users, misleading ⁠the public about their safety and illegally collecting data from users under 13.
