I would not be surprised if WhatsApp, since it’s been run by Meta, has been secretly gathering heaps of user data and tying those identifiers to their account data - regardless of if chats are truly still encrypted E2E or not. This complaint doesn’t seem to discuss user chat data explicitly?

It seems more like complaints of legal requirements being ignored after repeatedly being raised through internal channels to management, for years - eg GDPR, California Data Privacy Laws, etc being singled out as being breached.

This part stuck out to me though, as it seems very implausible to be true.

“Approximately 100,000 WhatsApp users daily suffered account takeovers with access to Covered Information, yet WhatsApp failed to implement adequate preventive measures.”

There are approx. 2 billion WhatsApp users. If 100,000 users daily are getting their accounts taken over, literally every account would be taken over in just five and a half years - and these complaints seem to date to 2022. I’m sure more noise would be getting made if that many users were suffering account takeovers daily? I’ve actually never heard of an account takeover and i know many dozens of Whatsapp users, though i stopped using it myself years ago after the Meta takeover. On its face this claim seems like a gross over-exaggeration?

Who’s waiting for them to lie to us? WhatsApp has always failed to include a libre software license text file, which means we’ve always been banned from forking it. We’ve never truly controlled it. Every decision, every update, every change comes from its owners, not us. We can never ensure it aligns with our needs or privacy values. We’re completely trapped in their every choice, with no way to force out abusive decisions. This lawsuit just proves what we’ve been losing all along, control over our own computing.
