Certainly there were diehard unrepentantly proud sexists in any class of “old techies”.* There was also never a class of “old techies” that didn’t include people who were informed by feminist analysis, or (before people called themselves “feminists”) an awareness of how gender inequality warped power hierarchies.
For that matter, I don’t think anyone using modern language to critique power relationships can do it free** from some “benefit of feminist analysis”.
*Boing Boing is probably not an ideal place for forgetting or erasing the contributions of some of the early techies. I don’t think you’re trying to do that, just noting the situational irony.
**Free as in freedom, not free as in beer.
