What kind of unknown things with an address book is WhatsApp doing?

The idea is that Meta uses WhatsApp contact lists to build and maintain their social graphs, which is in turn used for advertising.

WhatsApp uploads the address book from the user's phone to Meta's servers and after that it's unclear to outsiders what they do with it. Hence "unknown".
