WhatsApp Faces Privacy Lawsuit and Introduces High-Security Mode
A group of people from different countries have sued Meta and WhatsApp, saying that the app's end-to-end encryption doesn't really keep their chats private.
They claim that Meta employees can still read their messages.
Meta says this isn't true and that WhatsApp has been using strong encryption for ten years.
Some tech leaders, like Elon Musk and Sridhar Vembu, have shared their thoughts.
Musk suggested people use his platform, X Chat, instead, while Vembu criticized ad-based business models for creating a conflict of interest in privacy.
Meanwhile, WhatsApp has introduced a new high-security mode called 'Strict Account Settings' to better protect users, especially those at high risk of hacking, like journalists or activists.
This mode blocks media from unknown senders, disables link previews, and silences calls from unknown contacts.
This debate is about whether people can really trust that their messages are private on WhatsApp.
A lawsuit accuses Meta and WhatsApp of misleading users about the privacy of end-to-end encrypted messages.
Plaintiffs allege that Meta employees can access user conversations through an internal process.
Meta denies the allegations, stating WhatsApp has used the Signal protocol for encryption for a decade.
