You have given plenty of examples of morally wrong things being done for financial gain. That is not news. People have been corrupt and greedy for thousands of years.

What you have failed to do is show any evidence at all that companies are legally obliged to be corrupt and greedy.

On your link about warrantless surveillance, scroll down to the long section on legal issues. While there is no question that the government asked for, and got, a lot of that information, the legality of the request is quite a different matter.

And now for the concrete counter-example, when the NSA asked for Qwest's cooperation, they didn't get it. This decision has materially affected Qwest's financials because they were shut out of a lucrative NSA contract.

Now show me the shareholder lawsuit against Qwest for failing to maximize shareholder value by refusing the NSA on this matter.
