The sad fact is that laptops that are wedded to Windows often have no other way of performing low-level system operations. In some cases the BIOS may not even function correctly unless Windows at least remains in place. Likewise for some external hardware that needs Windows to initialise/update correctly but can otherwise function perfectly well under Linux. So your prescription is a bit glib.
(Now you may reasonably respond with "Then don't buy such cursed hardware!" and in spirit I agree, but for the laptop itself there is often a sizeable price/availability tradeoff in avoiding it, and for some bits of external hardware there may simply be no alternative at all. Again sad but true.)
