I'd like to post my perception since I was a 90s hacker.
Inclusivity is arbitrary here - no one in the scenes that I was familiar with were excluded because of race or sex - it's just that certain demographics weren't attracted to that 'scene'. Those like me, ADHD, awkward, and not extremely socially capable at the time, were however sometimes excluded. There were still the cool nerds and the lame nerds. I was pretty involved in the scene, being a staff writer of 2600 (several articles published under various handles, my name listed in the cover for a couple of years), and spending some time talking to "famous" people.
Later I grew up, spent 4 years in the military, then used money I earned to finally go to college, graduating eventually with an engineering Master's in my 30s. As I grew up I realized that the whole 90s / early 2000s hacker scene was mostly just a social clique. I learned that many people who were revered had marginal skills. I learned that the paranoia and self-aggrandizement ("The FBI totally monitors #2600 to learn our skills") was really just immaturity. The whole thing eventually seemed lame as I grew into an adult. I realized 2600 was really just a money machine and a manipulative scheme. Phrack went downhill quick, sadly (I also published there).
Still, this was a classic and wonderful time. Even I made friends - some that I talk to now, 20+ years later. I learned a lot. I got started on a tech path that took me very far and into regions of tech I'd never learn about otherwise like radio and telephone. I'm still a hacker, but legally. I don't miss the "scene" at all, but I do wish I was more included in it at the time. As this article illustrates it must have been great.
