The privacy policy literally includes that they do?

> We provide some non-personal data to our advertisers and strategic partners that work with Apple to provide our products and services, help Apple market to customers, and sell ads on Apple’s behalf to display on the App Store and Apple News and Stocks. For example, we may share non-personal data about your transactions, viewing activity, and region, as well as aggregated user demographics such as age group and gender (which may be inferred from information such as your name and salutation in your Apple Account), to Apple TV strategic partners, such as content owners, so that they can measure the performance of their creative work, meet royalty and accounting requirements, and improve their associated products and services.

I'm not refuting that they don't sell your data, I haven't checked. But your link is not relevant to the discussion.

It's the privacy policy of the Apple TV app, not the Apple TV device.
