How does the GDID compare to the UDID (Unique Device Identifier) and serial number in iOS; and the Apple Hardware UUID and serial number of Macs?

On the subject of serial numbers, the ones for your hardware and peripherals are also being transmitted as "telemetry", which gives them even more options to spying on you, ex:

1. If your printer has tracking dots [0] then a printed flyer can be tracked back to your computer, IP, and MS/Apple account.

2. If a device is reported on two computers, MS/Apple know there is some kind of connection between the computers.
