The monitors aren't installing anything. That headline was a lie.

It's Windows Update that's installing LG crapware upon seeing relevant hardware IDs. That's why the problem affected older monitors too - it's the update side that suddenly started to ship malware.

Another win for the Linux security model (software installed and updated manually from vetted repos only).

I guess with more and more consumer devices running Linux based OSes (SteamOS, Android, Bazzite, Silverblue, ..) that becomes more and more interesting.

And unfortunately the "I'm safe on my non-windows-system" argument doesn't count for long, as the 99% muggle crowd justifies a shift to a world where our non-certified (=> 'insecure') systems are not supported by big companies anymore, as it's currently happening on Android.
