You were playing a game without paying for it. How did you imagine they were making money without pimping your data?
I don't understand what this has to do with the topic at hand. Are you suggesting that people can't conceive of the sale of their data because they can conceive of whales amortizing the cost of their video games? That seems contradictory in your estimation of people's ability to grasp the world.
"How did you imagine they were making money without pimping your data?"
I imagined they were making money in the big obvious way they make money!
I can conceive of them selling user data, but it's not their core business model, and they would operate basically the same if they couldn't sell user data. It was never some obvious thing that they would do this.
