Very good point. I was about to jump into the prescriptivist-bashing fray - in fact, I upvoted subwindow's comment, and I can't take it back, since I don't have enough karma - until I took a look at the heading of the "article" and realized that it was in fact part of the Economist's style guide. It's clearly not meant to be accurate reflection of any up-to-date dictionary - look up pretty much any word in its list at www.m-w.com (e.g. "collapse" IS acceptable as a transitive verb) and you'll see they're way behind the times as far as common usage goes. Let them maintain their backward-looking editorial standards if they wish to do so for consistency's sake, and leave them be.
