Doing unethical things because "We had to so the shareholders would make money" is such a cop-out. I see it just the opposite way. You have a duty to do things ethically so that in the long run customers continue to want to use your product. So that governments don't start going after you for the unethical things you do. So that other businesses will trust you and continue to work with you.

Here's an example: Huawei. They've reached out to me saying they'll pay me more than my employer and my commute will be shorter. No effing way. I'm sure I could make them a lot of money, but they're history of unethical behaviour is an instant deal-breaker for me. Others will, sure, but in the market of labor they're going to have a reduced supply because I'm surely not alone in this attitude.

It's unfortunate. Profit of their shares is the only thing a lot of people look at (and willfully ignore anything else unless it slaps them in the face/becomes a major mainstream media event).
