Who said lawsuit? It doesn't have to be a lawsuit. Shareholders can put pressure on the company in a few ways. And in any case, I'm talking about shareholders' interests, not the (sometimes ineffective) steps they can take to remedy conflicts with corporate leadership.

Nonetheless, a lawsuit is possible as well. Foregoing profits in favor of ideology could conceivably be a breach of fiduciary responsibility, a primary cause of shareholder lawsuits. You may be right that there has never been a lawsuit like this about too-low prices, but I simply don't know. And unless you're a corporate lawyer with extensive shareholder lawsuit experience-- or happen to have some legal experience and a subscription to something like Westlaw-- then you are making an unfounded guess.

I have a friend w/ Westlaw access, among other databases, but I'm not willing to ask them to spend a few hours researching the issue to see if there's every been such a case, or try to find one myself. But in the history of corporate lawsuits it certainly wouldn't surprise me. There is a body of caselaw that could encompass it, predatory pricing (https://www.justice.gov/atr/predatory-pricing-strategic-theo...). Selling significantly below the market-clearing rate demonstrated by scalper prices might provide some ammunition for this claim, but IANAL so I won't speculate further on its actual applicability.

If you have more direct expertise or knowledge of the caselaw there I'm happy to hear it. I think, absent completely recalcitrant corporate leadership on the issue, shareholders would force the issue outside of the courtroom.
