this is really shocking. wouldn't browser makers concerned with privacy like librewolf, mullvad, ungoogled-chromium, etc, try to block this by default? is it that they don't know? is it that it can't be blocked?
how does a regular user of a typical linux distribution like fedora or debian block this?
is this machine-id used to track people on hardened distros like tails or qubes?
can this machine id be read by sites when using tor browser?
i don't understand why debian, for example, who removed telemetry from keepassxc before putting it in their repo because they didn't like a password manager phoning home, would allow a persistent id that could be easily read by many sites.
