To do what though?

One possibility would be to build a more accurate social graph. So, let's say you have 500 friends on Facebook, but only 50 of those are people you speak to on a regular basis. This helps Facebook better understand your preferences based on your online interactions and the people who you associate with on a regular basis. You are the average of the 5 people who you spend the most time with, or something. This hopefully means that they'll be able to show you better ads.
People who aren't on your contacts list probably aren't your friends. :)
to drive down advertising costs.
Is it not also true that Whatsapp is (was) a competitor to FB? I mean, if I wanted to get rid of FB, the only other place I know I can reach the majority of my contacts is WhatsApp. Now since they own both I have no non-FB alternative.
