Yes, we can all agree that E2EE means FB isn't reading your messages and using that data (like they do, for example, in FB Messenger / IG messages). But the metadata is still valuable, and not encrypted, and is probably how they're making money with the product.

I can't attest to this metadata but it's just worthy to note Facebook starting telling shareholders this year that they have "limited visibility into WhatsApp user activity due to encryption".

A closed-source App could send the private key to a server. I hope WhatsApp doesn't do that.

They absolutely could. But, given the popularity of FB properties, I'm sure there are several groups who decompile their releases on a regular basis and I'm sure there'd be a lot of screaming if the E2EE wasn't implemented properly (see: the Zoom E2EE debacle).
