The case is less about broken encryption than about how privacy is sold to users.
One thing we have always loved about WhatsApp is their claim that messages on the platform are end to end encrypted. However, the green app is facing a newly filed lawsuit that questions what that promise truly covers and, more importantly, what it leaves out.
What this dispute has brought to the fore is the disconnect between how encryption works in theory and how privacy is understood by everyday users. For us to understand why the lawsuit matters, it is necessary to look beyond slogans and examine the mechanics of WhatsApp’s system alongside the specific practices the plaintiffs say undermine its privacy assurances.
When they say end to end encryption built on the Signal Protocol, what they practically mean is that a message is encrypted on the sender’s device, travels across the internet in an unreadable form, and is decrypted only on the recipient’s device. The company’s servers act merely as a delivery system and, in principle, cannot read the content of messages passing through them. This protection applies to private chats, group conversations, voice and video calls and shared media such as photos and voice notes.
On a purely technical level, this form of encryption is real and widely respected. And so here is the thing; The lawsuit does not claim that WhatsApp lacks encryption in transit or that Meta routinely intercepts message content. Instead, the case focuses on everything that happens around encrypted messages and how those surrounding processes are explained to users.
One of the central issues raised is metadata. While message content may be encrypted, information about the communication is not. This includes who is messaging whom, how frequently they communicate, the timing and duration of conversations, the devices involved, phone numbers, IP addresses and approximate locations. According to the plaintiffs, this data can be highly revealing when aggregated. That it is capable of mapping personal relationships, political networks or even business activity without ever opening a single message.
The lawsuit argues that WhatsApp’s emphasis on private messaging obscures the significance of metadata, especially given Meta’s broader data driven business model. By foregrounding encryption while downplaying the power of metadata analysis, the plaintiffs say the company is not being truthful. That there is a misleading sense of total privacy.
Another major point of contention concerns message backups. WhatsApp encourages users to back up their chats to cloud services such as Google Drive or iCloud. For years, these backups were not protected by end to end encryption by default. As a result, cloud service providers could technically access stored messages, and law enforcement agencies could obtain them through legal requests directed at those providers. Although WhatsApp has since introduced optional encrypted backups, the lawsuit contends that users were never clearly informed that their supposedly private conversations could become far less protected once stored in the cloud.
In legal terms, the issue is not whether encrypted backups exist today but whether users were given a clear, plain language explanation of when encryption did not apply. The plaintiffs argue that this gap between perception and reality undermines WhatsApp’s core privacy messaging.
The case also examines how reporting and moderation functions interact with encryption. When a user reports a message, the reported content is forwarded to WhatsApp, sometimes along with recent messages from the same conversation. In addition, the platform relies on automated systems to detect spam, abuse and other harmful behaviour. The plaintiffs argue that these processes demonstrate that WhatsApp can, under certain circumstances, access or process message content, contradicting the absolute impression created by repeated claims that messages are inaccessible even to the company itself.
Meta maintains that such access is user initiated and essential for safety and abuse prevention. The lawsuit does not deny the importance of moderation but argues that the existence of these mechanisms should fundamentally alter how WhatsApp communicates its privacy guarantees to users.
It is important to note that the lawsuit does not accuse Meta of secretly reading everyone’s messages. What it does, however, is allege that WhatsApp’s privacy claims are framed in overly absolute terms and that ordinary users are likely to interpret phrases such as “end‑to‑end encrypted” as meaning complete and unconditional privacy. According to the plaintiffs, this amounts to consumer deception rather than a failure of encryption technology.
For billions of users worldwide, particularly in regions where WhatsApp functions as social, political and economic infrastructure, this distinction matters. Encryption protects messages from hackers and interception. Transparency, on the other hand, protects users from misunderstanding the extent of corporate access and influence.
Ultimately, the lawsuit forces an unsettling question. When technology companies promise privacy, are they speaking as engineers describing narrow technical safeguards or as marketers selling reassurance? The court’s answer may shape not only WhatsApp’s future but how digital privacy is explained and trusted across the tech industry.
