When a large, publicly traded ad-company (that relies on collecting data and tracking users for most of it's income), creates a product that costs them quite a lot of money to make, and then gives that product to you for free...
Do you expect them:
A.) to be taking a loss on that product because they really just want to gift it to you from the goodness of their heart with no ulterior motives?
B.) to actually have another way to make money from that product, which makes the whole endeavor financially worthwhile to them?
