SAN FRANCISCO (Diya TV) — Meta Platforms is again facing sharp questions over user privacy after a new lawsuit claimed WhatsApp private chats are not as secure as the company promises. The case, filed in a U.S. court, alleges that Meta misled billions of users worldwide by suggesting their messages are fully protected by end-to-end encryption.
The lawsuit has renewed global debate about digital privacy, trust in Big Tech, and the real meaning of encrypted messaging. Meta has denied the claims and called the case baseless. Still, the allegations have drawn attention from regulators, privacy advocates, and tech leaders.
The complaint was filed on Friday in the U.S. District Court in San Francisco. An international group of plaintiffs accused Meta and its WhatsApp unit of deceiving users about message privacy. WhatsApp has long told users that only the sender and receiver can read messages. The app displays a notice saying chats are protected with end-to-end encryption by default. The lawsuit argues this claim is misleading.
According to the filing, Meta allegedly stores, analyzes, and can access a large share of WhatsApp communications. The plaintiffs say these practices contradict WhatsApp’s public statements and in-app notices. They accuse Meta and its leadership of defrauding users across the world. Bloomberg reported that plaintiffs come from several countries. These include Australia, Brazil, India, Mexico, and South Africa. The wide geographic reach adds weight to the case and suggests the concerns extend beyond one market.
One of the most serious allegations is that Meta employees can access the substance of WhatsApp messages. If proven, this could challenge how encrypted messaging services operate and how they are regulated. The lawsuit claims “whistleblowers” exposed these practices. However, it does not name them or detail their disclosures. This lack of detail may become a key issue as the case moves forward. Courts often demand clear evidence when claims rely on unnamed sources.
Privacy experts say the case could test public understanding of encryption. End-to-end encryption means only users hold the keys to read messages. Companies typically say they cannot access content without those keys.
Meta has rejected the lawsuit in strong terms. The company says the claims are false and misleading. It also plans to seek sanctions against the lawyers who filed the case. Andy Stone, a Meta spokesperson, dismissed the allegations outright. He said any claim that WhatsApp messages are not encrypted is “categorically false and absurd.” Stone added that WhatsApp has used the Signal protocol for end-to-end encryption for about a decade.
Will Cathcart, the global head of WhatsApp, also responded publicly. He said WhatsApp cannot read messages because encryption keys stay on users’ phones. He said the company has no access to those keys. Cathcart described the lawsuit as a “headline-seeking” effort with no merit. He also noted that the same law firm has defended NSO Group, whose spyware has targeted journalists and officials.
The controversy gained more attention after Elon Musk weighed in. Musk, the owner of Tesla and the social platform X, questioned the security of major messaging apps. In a post on X, Musk wrote that WhatsApp is not secure. He also cast doubt on Signal, another encrypted service. Musk urged users to switch to X Chat, his platform’s messaging feature.
His comment spread quickly online and added a competitive edge to the privacy debate. Critics noted that Musk did not provide evidence to support his claims. Supporters said his remarks reflect growing public distrust of large tech companies.
The lawsuit arrives amid rising global concern over data privacy and surveillance. Messaging apps play a central role in daily life. Many users rely on them for private conversations, business deals, and sensitive discussions. If the court allows the case to proceed, it could force closer scrutiny of how encrypted services operate. It could also push companies to explain their systems more clearly to users.
