From the second link:
"People opposing the plural use base their argument on the fact that none comes from the Old English word an, meaning “one.” But the citational evidence against restricting none is overwhelming. None has been used as both a singular and plural pronoun since the ninth century. The plural usage appears in the King James Bible as well as the works of John Dryden and Edmund Burke and is widespread in the works of respected writers today."
I enjoy Alan's resistance to every correction Steven lays on him. You're wrong Alan. No I'm not. Its entertaining in an annoying little brother sort of way.
