Re: Can you spell lawsuit?
Wow, not all that bright.
Whilst I'm not a fan of this 'plan', it's more an unintended consequence of someone finally (finally!) deciding it's time to stop dragging legacy shit around for a free ride. UEFI has been out long enough but we still seem to have options to run legacy BIOS. xHCI has been out long enough but we still seem to drag around the legacy *HCI interfaces to support 'native not USB3' ports.
For Microsoft, this is a no-brainer. If they say it's supported, but you need the *right* installer then you have far too much of the population with the wrong media stirring up a storm over their lack of understanding. If they say it's not supported, people stay on Windows 10 and get over themselves or move on to Linux. Still cheaper to lose a few from the fence than it is to staff the support desks for the onslaught of the morons.
