It’s blinders. Plain and simple. I’ve worked with too many developers who will pander for money. A few that tried to shame me for not being on board (my life skills tell me calling someone a whore in a team meeting is a bad career move but it doesn’t stop me from staring at them and thinking it). When enough money is on the line principles get set aside. We like to think our cohort are above this sort of thing but the evidence clearly doesn’t support it.
