The Jobs quote on page 2. All iOS devices and all M1 macs maintain a persistent serial-number-linked connection to Apple at all times, even if you don't use iCloud, don't have an Apple ID, don't use FaceTime/iMessage, don't use the App Store, and have analytics turned off. No indication that this is happening is displayed, and there's no way to turn it off.

Your client IP discloses the city the device is in, and the ISP. This means that Apple has a city-level, ISP-level location tracklog of every iOS device and all M1 macs (and possibly intel macs too) by serial number.

You're not asked, you're not even told. This is the exact opposite of their headline founder quote on the first non-title page of the doc.
