This is an NPR article in 2021 that discusses how Facebook elected not to notify its users of a potential data breach. This data was found by misusing a feature on Facebook where you could search people by phone number. Facebook elected not to tell people about it claiming that they did not know who they would need to notify. The article ends by showing that Facebook has struggled with user privacy before, having to settle for $5 billion dollars for breaking an agreement to protect privacy in 2019.
