"Naive-utopian hacker culture" gave us approximately everything we are building upon right now. Can't tell the same about SJWs. And yes, they are very much the same as those who call to class warfare and unionizing. Those are people who interested in shifting the power from the people who actually build things to those who will dictate them what to do and what not to do.
I'm almost 60. I'm a part of the "naive utopian hacker culture" - I started working on the GNU project in 1986. And I'm telling you that this conception of it - as something alternative to political power, class warfare (or at least, an understanding of class) and "that old stuff" - is just completely invented bullshit (invented in part by ESR, who I went out to a rave with back in 97).
I built/build things ... and I'm telling you that your analysis is wrong. Yor antipathy towards what ESR terms SJWs and to unions and the understanding that a class war has been ongoing whether you want to admit or not is blinding you to reality that "naive utopian hacker culture" might have been a good driver for technological "innovation", but it has never been how the world works, nor will it be.
