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.
also there's the TPM chip.
Upvoting both comments for awareness, since Linux is the first of a multi-step process, not a privacy panacea.
But we must be clear that in both theory and practice there’s little comparison between systemd and modern Windows machine-user association.
Someone using Windows regularly has a gaping wound, is actively bleeding out. Switching to Linux is just a tourniquet, but every other treatment is at best no-effect until that tourniquet is applied.
E: transpose
systemd/Windows for clarityPlease elaborate on what u are referring to with regard to systemd machine user association?
I’m specifically highlighting that there is none though I acknowledge machine ID makes it easier.
ETA: edited original comment to be more clear
