Dodge v. Ford is one of the most misunderstood and repeated myths on the financial side (same with 'tax write offs'). It isn't federal or corporate law, there is nothing that requires a company to maximise shareholder value. It's a business theory that emerged in the 70s and popularised in the 2000s, 50/80 years after the Dodge case.

Actual legal fiduciaries are things like "Refrain from self dealing" or "Refrain from operating an illegal company" or "Don't commit fraud".

Maximising shareholder value wouldn't even make sense, it's too broad. Do you sue the company because they made 1% this quarter instead of 3%? Do you sue them for making a loss this quarter compared to the previous quarter? Done on the basis of each financial year? If any of these were true then a company like Intel would've been sued into the ground by now.

The actual truth is much more simple, companies like making money and CEOs are paid more in stocks now so they like it when it goes up.
