My guess is that you agree, when you allow an application to track you for functionality purposes (such as using Google Maps or Apple Maps, just to name two) that they can use your data. And then they sell it to someone who want it for marketing. Or law enforcement. Or politicians. Or someone trying to uncover a crime.
I think True the Vote got a $2 million dollar grant that allowed them to purchase it.
It’s all money. Remember...you are not the customer. YOU are the product.
