Tell us more about how you use your phone without activating it with a SIM card.
Google sells your data for ads. Android wouldn't be profitable without it. Apple gets its money elsewhere and is not interested in selling its customers' data.
That's the difference. With Google, your data escapes Google's possession, whereas with Apple, it doesn't.
I'll never stop finding it hilarious how Google-colored your nose is sometimes
Google doesn't sell data, they sell ad space based on the data they gather. -_-
