This appears to me to be unrealistic or performative, except if you mean pushing back in the sense that anyone could, as a voter for example. Boycott of defense work won't work; attempting to claim some special authority in debate won't work either.
Too many nihilists in the tech industry with the attitude “if I don’t do it someone else will”, and here we are as a professional class actively making the world an objectively shittier place. The VCs can’t do it without us.
This is one of my personal bugbears. I keep making this point on HN but devs want to LARP as professionals so they usually don't want to hear that they have more in common with retail workers than they do with carpenters, engineers, or accountants.

I’d be willing to pay a few hundred dollars a year to be a part of a professional organization that maintains ethics requirements at this point.
