It really doesn’t. First, that’s a Michigan case interpreting Michigan law. Almost every non trivial US company is incorporated in Delaware and subject to Delaware law.
Delaware law does have somewhat similar cases, eBay v. Newmark is a good one to read but …
Second, in both the Ford and Craigslist cases what was happening was really blatant. Courts are not in the business of deciding this or that corporate policy isn’t instantly maximizing shareholder value. What they won’t necessarily let you do is announce that you, being a controlling shareholder, never ever intend to make money and it sucks to be a minority shareholder.
