The issue is quantifying this sentiment. How would you even identify programmers who are doing this? Yet another reason why software engineers really ought to organize their labor like a lot of other disciplines of engineering have done decades ago. Collective action like this would be more easily mustered, advertised, and used to influence outcomes if labor were merely organized and informed of itself.

You can do public pledges, e.g.: https://neveragain.tech

I would bet there are a hundred thousand people refusing to work in war, ai, ads, gambling, crypto etc. I certainly am. But all it means is that pay goes up and quality of engineering goes down a little in those sectors, but not much more.
