WhatsApp is end-to-end encrypted. No one at Meta can read your messages.

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.

You can't unless you've chosen to back up your WhatsApp messages to iCloud/Google in which case it's Apple/Google responsible for preserving the messages and subject to their encryption standards, nothing to do with Meta.

Try logging in on a new device and putting your main device into aeroplane mode as soon as the login succeeds. Loading of old messages on the new device will stop.

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

Moxie Marlinspike (founder of Signal) [0]implemented the same E2EE algorithm as Signal (Signal Protocol) into WhatsApp, but that was 10 years ago, so who knows if things have changed since then.

Practically speaking, it isn't secure; no closed app can be. It receives regular compulsory updates (old versions refuse to work) and there's nothing at all stopping Zuck from sneaking in backdoors targeted at you personally.
