That's a pretty wild claim. What's legacy for you? I'd consider legacy e.g J2EE crap running on web[sphere|logic] as holding most of the points in that league table vs COBOL.
Pretty much every business I've worked at to date has had such legacy software, which was inevitably still used in some contexts.
It's not always obvious, because - following with the previous example numbers - only 1-2 Java devs will have to interact with the legacy software again, hence from the perspective of the remaining 98, Cobol doesn't exist anymore.
J2EE would be late 90s and 2000s.
