Corporations are always happy to pander to morality when it's to their benefit, but I believe corporations are inherently amoral. They might make decisions that are moral, but that's just a happy coincidence that occurs when the decision that's in their interest also happens to be the moral choice. Corporations are equally happy to make choices that most would consider immoral, if it meets their goals.
I have no source for this, but my theory is that when the workforce of a corporation grow past Dunbar's number it will inherently bend toward amorality. Making moral choices requires knowing the people affected by your choices, and having empathy for them. Once it becomes impossible for one worker at a company to have a personal relationship with every other member of the staff, it's all too easy for groups to form within the company that will make choices that drive the company's goals (growth, revenue, profit) at the expense of anything and everything else (the environment, the community, their customers, even their own workers).
