Saw this exact claim on a billboard not too long ago

It's a strangely worded statement. What about data collection, metadata, other third parties

Maybe it's related to the fact that plaintiffs lawyers are now trying to verify what's going on inside Meta with WhatsApp through litigation discovery:

Meta's motion to dismiss seemed a little weak. Time will tell

Hearing will likely be sometime this summer

If I can log into whatsapp on a new device and old messages aren’t encrypted then they have a copy of your key and it is not true e2e encryption.

How are we sure that it is really end-to-end encrypted?
