Well, it depends. Zuckerberg has controlling interest in Meta even though he owns a minority of it (<15%) because of its dual share structure. Meta will do what he wants it do.
Not even really true anymore. It’s all about “stakeholder capitalism“ now, which boils down to management being able to prioritize whichever stakeholder it wants to in any given situation.
Shareholder primacy may not be perfect, but it at least constrains management instead of giving them completely free rein.
