> Do you really believe that a hostile group would have difficulty finding important infrastructure to attack without an open infrastructure map?

I honestly do. A large part of what protects open, free societies is that the smartest people generally have better things to do than blowing shit up. If you’ve ever taken a close look at any heavy infrastructure, it should strike you how easy it would be to break into and disable (particularly if you aren’t concerned about getting caught).

On the balance, I still prefer these data being open. But there probably is a domestic-terrorism risk that’s amplified.
