As I've previously noted, Google depends upon data to serve its customers - and the average person who enters a Google search is probably NOT one of Google's customers. The advertisers are.
So why should anyone turn personal data over to Google, Facebook, or whoever?
Google is making its case.
The basic premise is that if you give your data to Google (and its customers), Google in return will make your life better. Based upon your personal data, the information that Google provides to you will be more beneficial to you.
For example, if you have entered a search "How can I join the Woman's Christian Temperance Union?" Google will be smart enough to NOT show you The Most Interesting Man in the World.
