A group of WhatsApp users from multiple countries has filed a lawsuit against Meta Platforms Inc., alleging that the company falsely promotes end-to-end encryption while secretly storing, analysing, and accessing the content of private chats, constituting a serious breach of user privacy.
The class-action complaint, lodged in the US District Court in San Francisco, involves plaintiffs from Australia, Brazil, India, Mexico, and South Africa. They claim Meta and WhatsApp mislead billions of users worldwide by asserting that messages are fully private and secure due to end-to-end encryption, when in reality the company can view and handle the substance of communications.
Allegations of false privacy promises
According to reports from Bloomberg and other outlets covering the filing, the lawsuit asserts that Meta “stores, analyses, and can access virtually all of WhatsApp users’ purportedly ‘private’ communications.” The plaintiffs cite whistleblower accounts as supporting evidence, though specific details or technical proofs were not elaborated in initial public summaries of the complaint.
This challenge directly targets one of WhatsApp’s core selling points – its end-to-end encryption, which the app has long advertised as ensuring only the sender and recipient can read messages, with Meta or any other party not in a position to access content. The suit argues these privacy assurances are deceptive and fraudulent, potentially violating consumer protection and data privacy laws.
Meta’s response to the allegations
Meta has strongly denied the allegations, describing the lawsuit as “frivolous” and reaffirming WhatsApp’s commitment to security. A company spokesperson stated that end-to-end encryption prevents Meta from reading message content, and the firm plans to defend vigorously against the claims.
The lawsuit emerges amid heightened global scrutiny of Big Tech’s data practices, following previous controversies involving WhatsApp’s privacy policy updates and regulatory fines in various jurisdictions, including India. If granted class-action status, the lawsuit could represent millions of affected users and potentially seek damages or injunctive relief to change how Meta handles WhatsApp data.
While technical experts have long noted that end-to-end encryption applies to message content in transit and at rest on devices but not necessarily to metadata or backups, the new lawsuit appears to push further, alleging direct access to chat substance by Meta personnel or systems.
