The tech job market is extremely buoyant in the present age, meaning very few programmers are in a position where they have to settle for a job they dislike just to make ends meet.
I mean, every tech company talks about wanting engaged, passionate, proud employees - so why settle for doing work you can't take pride in when you could switch to work you could be proud of, and probably get a raise while you're at it?
No doubt it depends on the range of things you could take pride in doing, which varies from person to person!
So yeah, you could find a job doing something that isn't morally questionable pretty easily, even in most fields.
Consider how every industry can benefit from having a developer doing job automation, looking at data for optimization, or making new products.
The demand is ferocious.
I don't understand why developer wages are lower outside the US. Shouldnt developers everywhere be changing local industries?
And also, I think he/she means if you can't get behind what Facebook is doing, maybe jump to Apple who "supposedly" have security and privacy as their top priorities and in the mean time receive a raise.
Not everyone is top talent though - and I don't think there's anything wrong with being an average programmer and not wanting to work on morally wrong projects.
