There no "the tech world", there's just people who are, indeed, choosing what they do and do not want to fight about. If you feel so strongly about this, get people involved, get a Twitter campaign or boycott going, and just like in every other such situation, if enough people make noise then you may or may not get results. Much like open source, if you see a problem and do nothing, that's on you, not the community.
There's no inherent need for balance (like you seem to want: https://news.ycombinator.com/item?id=7623043 ) in people exercising their free speech. If it bothers you, do something about it.
I disagree that there's no "tech world". Maybe that's the wrong term but hey.
I do feel strongly about bad behavior (and I try to do some small parts)–but not about the lack of balance. I just find it intriguing and possibly worthy of discussion. I'm inclined to call it "hypocrisy" but maybe that's not the correct term.
I'm naive enough to think I can change what people choose to fight. Like open source, sometimes you find a bug but don't know how to fix it. What can you do besides submit an issue in GitHub?
