There's a very easy trick to defeat this: use Linux.
If your system uses systemd, it has an etc/machine-id, which is used for a lot of different things. And changing it will break a lot of stuff, probably until you reboot. I guess you could write something to randomly shuffle it every time you reboot? But it is the go-to way for lots of programs (including browsers) to identify themselves. Which means (unless you have done the work to scramble your machine ID) you can be tracked on Linux as well.
The difference is that Linux isn't sending telemetry to some central entity associating that ID to an IP.
This article is super vague about this as well. How does Microsoft not only have the GDID->IP link, but they have Web history as well? Are they just exposing all this through advertising telemetry?
Fucking gross. And if you know of anything on Linux exposing/transmitting the machine-id, please do let everyone know because nothing should. Anything that does should be considered malware.
i think i remember hearing the dbus machine-id being read by google chrome on linux. it could be used for privacy violation with proprietary software, though i personally consider linux machines with chrome or equivalent software installed compromised.
