Famously, the Linux kernel does not have a stable ABI for drivers. As a result, by far the majority of drivers are in-tree, maintained by the kernel folks as part of the kernel.
The Linux approach has the downside of not having the drivers if a vendor has not been working with the kernel community before launch (or for those who haven't upgraded to a kernel that has the driver, e.g. a LTS release).
On the other hand, the driver is maintained by kernel developers, not created by the hardware developer who is not getting paid after they sell the device. This helps avoid abandoned / vulnerable drivers, or having the hardware dev search for... alternative revenue streams, as in this case.
If you're trying to say that Microsoft implemented a method of delivering specifically malware executables to every PC, I've got a bridge to sell to you.
No, what I'm saying is that Linux isn't safer simply because "it's not relevant enough to be targeted", it's safer because it doesn't offer mechanisms which could be abused to do this.
Nobody is diminishing LG's blame, LG is guilty of installing malware, and Microsoft is guilty of being grossly negligent and facilitating it. Microsoft implemented this feature knowing that it would eventually be abused for something like this, and it's bad enough to be indistinguishable from malice.
