Right. And that's often missed. The hacker ethic and the FSF project are fundamentally countercultural to the Big Iron mentality of the 60s-80s. In the 90s it started getting sanitized by the Open Source folks, and the collision of Big Money and Software in the 00s subverted and subsumed the whole business.
But there are still many people who hack for the sake of the hack. They are often looked down on... it's still countercultural to the modern software/VC world. :-)
I broke into my first mainframe in 1977 because I had to if I wanted to play Colossal Cave Adventure. :)
I learned to blue box because I had to if I wanted to talk to my friends around the world and couldn't afford the phone bill.
I tell people now that if you want to pen test, cool, grab some VMs and go nuts. You might even get a bug bounty or two...
I still like terminals; even on my 3k laptop (which is largely for gaming).
