Holding firm to a strong sense of ethics and morals is a risky thing to do. Whether you're representing a company, or just acting as an individual. But that risk does not justify NOT holding firm.
So, if you run a company, and you're afraid of getting sued by your shareholders for not pursuing profit at the expense of your ethics and morals, I'd suggest finding a new job. Or, just maybe, your shareholders aren't so blinded by greed that they would not support your company doing what is right.
