Same as every other org that incentives you to use channels that leak your data. They use it to extract more value from you, whether it's selling your data, buying your data from other vendors to augment their first party data, or a combination of both.
My dark dirty secret, as someone who frequents fast food restaurants, is that McDonalds is... actually not that bad, even good, and at the least it is very consistent and good value (if you use the deals, sometimes even without) and the people who think it's disgusting are just engaging in a little classism and can go home and watch Super Size Me again.
