The monitors arent pushing the software over USB. When Windows detects an LG monitor it installs the software. This is doesnt require the monitor to do anything other than identify itself as being LG.

The issue is, manufacturers are only going to get more and more insidious with this until they either have full unfettered control over what you are allowed to view on your own screen, or are stopped in a meaningful way by strong regulations.

HDMI and USB-C inputs can both potentially carry an Ethernet signal, bypassing a need for WiFi permissions.

Devices could look for and join hidden/ghost mesh networks from other complicit manufacturers devices without permission.

Device drivers could be bundled with software which will enable tracking through the connected machine.

Hell, we’re fast approaching the point that every TV could be equipped with a basic data SIM designed to directly phone home and act as a kill-switch once a device has been deemed EOL after its warranty expires.

I’m not saying that these are already in place just yet, but that we are well and truly oblivious, slowly simmering frogs.
