Huh? Another dose of reality:
I need to pay rent, pay medical bills, eat, and survive. As long as I'm dependent on an income to do that, I do whatever the employer wants as long as it's legal.
When I'm financially free, I'll have the space to think about the ethics of my work.
You want better? Fix the system so that I'm financially free earlier in life. Tax me less, charge me less rent, give me free healthcare, and let me save up cash for the rest of my life. When the system has delivered that OKR to me, I'll be able to put ethics first going forward.
Until then, I still need to earn money to survive.
I worked for Amazon for a couple years. Not on the above project, but nevertheless, I did what I was told. One of the reasons I went there was that I needed a surgery to replace my implanted defibrillator, which my life depends on, and (a) Amazon's sponsored health insurance would pay for it (b) Amazon's cash comp would be enough to hire lawyers to fight with insurance if necessary. Insurance companies usually pay what they're supposed to if there is a big tech HR behind it; they have a habit, in my experience, of not paying out what they're supposed to if they don't have something to fear. I was in startup land before, and often couldn't pay my medical bills (because insurance would cop out and not pay, and I didn't have money for lawyers to fight them) and had to forgo critical cardiac imaging procedures during that time.
