Nothing non-sense about it. The world is full of devices which do more than the basics. If you want to actually use the *advertised features* of your device you need some ability to install something requiring admin privileges.
Take LG OLED monitors. Sure you can plug them in and they'll display video. IN THE WRONG COLOUR because 100% of OLED screens don't follow sRGB colour formats, and therefore you will require fetching something online about the model to make the device work properly.
My keyboard? Yeah it'll type, but that's it. It is advertised with the ability to sync lighting to the game I am playing. That doesn't work out of the box. I need some way of getting something online for it.
If all you want is the basics, more power to you. Most consumers actually want their features which were advertised to them to work out of the box.
What do you think how this goes if somebody manages a supply-chain attach on this, especially on, say, an industrial control system that cannot simply be turned off?
IT CAN SIMPLY BE TURNED OFF. There's literally a windows setting to disable both installation of drivers via Windows Update, and installation of any software from driver manifests. You not knowing how to use your computer is not a problem for industrial systems who presumably have competent people managing their computers.
