When Microsoft came along with Vista, Stardock used it as a convenient excuse
You 'may' call it an excuse, but it's simply a reality.
If third party app companies do NOT chase the OS updates they will be left in a 16 bit mess of Win 3.11 or worse.
Outside demands placed on these companies by the OS provider [ie. Microsoft] tax their resources.
It perhaps would be nice if an OS stayed unchanged and unrevised for 10 good years at a time...but that has never happened yet.
