HN doesn't like your tone and you are being down voted. But in general you are correct, Linux and bsd users are less affected by such shenanigans.

Short personal story:

I had a win10 machine were HP kept installing some "analytics" service. This happened even on a clean windows install so I guess they used the same delivery mechanism LG is using here. After having read the HP ToS (where they basically gave themselves unlimited rights to monitor anything I did on that machine), I decided to wipe the disk and install Linux.

But I guess it is just a matter of time before EU or US make spywares mandatory on Linux too. Chat control and age verification seems to be the first step towards that.

I don't know about the BSDs but in Linux the reason is that a volunteer (in principle it could be a paid employee, I guess maybe it is for RHEL etc?) decides what gets installed

It is absolutely possible that when you plug in an LG display it installs and runs software on your Linux system†, just that rather than "Somebody at LG who earned a bonus" the decision maker was Sara in Portugal who fat fingered a change when trying to make a Python script for a PCI digital TV receiver work properly on 32-bit.

It does feel more like an amusing mistake in that case whereas even if LG tells us it's a mistake we know it was to earn $$$.

† Obviously YMMV but such "plug and play" features are commonplace because they're useful

Not only Linux/BSD, but MacOS. Not that Apple isn't annoying either, but it tends to avoid the windows bloatware stuff.
