"Probably the Queen knew quite well what he was thinking; for she knew, though Edmund did not, that this was enchanted Turkish Delight and that anyone who had once tasted it would want more and more of it, and would even, if they were allowed, go on eating it till they killed themselves."

The article actually points that out too, but glosses over it: "(To be fair, it was enchanted. But still, Edmund. Still.)"
Seems like an important point though. Yes, Edmund liked turkish delight enough to ask for it in the first place, but once he had the Queen's Turkish Delight he was more hopeless than a heroin addict desperate for their next fix.
As an aside, I can't believe we're debating Turkish Delight and "The Lion, the Witch, and the Wardrobe" on Hacker News.
