/etc/machine-id also exists

But you don't have a service uploading it along with the URLs you visit, which is the creepy part. The ID itself can be useful for your own administration. And if such a service were to appear, it could easily be removed. Everything in Linux is optional, especially as long as you stick to open source.

  • How do we know? Does anyone check for things like this?

    Many, many apps read /etc/machine-id if you do a quick github search.

    Apps may have been silently correlating our activity for years without us knowing.

    We know DHCP, EFI, GNOME, popularity-contest and many other apps already use it. There are countless ways it could be used already that are hard to detect.
