Meta plans to monetize WhatsApp by introducing advertisements in the app's Updates section, despite assurances that personal messages will remain private. Privacy experts express skepticism, citing Meta's history with data handling and the potential risks associated with ad-targeting based on user data.

A former security chief of WhatsApp, Attaullah Baig, has filed a whistleblower lawsuit against Meta, alleging that the company failed to address significant cybersecurity flaws that jeopardized user data privacy. The lawsuit claims that around 1,500 engineers had unrestricted access to personal user information, violating a previous Federal Trade Commission order. Meta has denied the allegations presented in the lawsuit.
