Yeah, that's why the stated explanation sounds weird.

Suddenly advertise this never-used block, and you're just going to get a massive torrent of previously-internal traffic from bazillions of organizations all over the planet that used it for something internal and were slightly lazy and didn't set up their routing quite right. Probably 99.9% of it is of no use whatsoever to anyone outside that org. It's tough to imagine that anyone thought they'd get any useful information on any hostile CCP activity by doing this.

I would also expect that any department doing hostile things on the net would be at least smart enough to not let any of their internal traffic leak out like that, no matter who they actually worked for.
