If someone was going to steal company info for a competitor, they’d do it before they gave notice that they were leaving. And they wouldn’t tell their current employer where they were going.

This might catch extraordinarily stupid people from conducting industrial espionage, but really I see it as the company encouraging people to not give any notice at all (which, remember, is just a courtesy) when they quit. It’s shortsighted on the company’s part.
