I was super into reverse engineering and loved the challenge. It seemed at some point "cracker" moved away from someone who can break software protections through reversing to someone who uses tooling to break into systems, without understanding how computers work. I still prefer "cracker" as someone who can reverse and break software protections.
Also, Thanks for helping out with Defcon! Been there a couple times and plan to go again. At the next live con i'm down to meet and talk about hacker lore!
