You do not know how much (if anything) Google was charging Apple for API access or if it increased when they generally increased the pricing. They almost certainly got a better deal than general users of the API because they are Apple and have a massive user base. We do know that Apple and Google had a contract in place but beyond that we don't know anything.

Furthermore, Apple does not get their data from "Apple Maps". They pay to license it from TomTom and other companies (though they do, of course, also produce data of their own that gets combined with the third-party sources to produce the aggregation that is Apple Maps).

I don't know how much you meant by "millions of dollars" but it was probably substantially less than the $267 million Apple paid to acquire C3 Technologies to add 3D maps to their offering.

Apple's decision was a great long term decision for them but it did hurt users in the short term (hence Cook's apology).
