Yes, that's true. What I wanted to point out is that a good idea in theory can quickly turn into an instrument that's being used for other purposes.
China is a great example to be studied in this regard. Their changes do indeed ensure that profit will only be one of several considerations for company policies in China; this will undoubtedly result in more consumer-friendly corporate behavior, but it also tightens central control and is likely to deepen the kind of censorship measures that I personally would not want to wish on any person or company.
Letting all people (of a given country) have a say means involving the government in which the company's headquarters are located. I'd rather not have national[istic] interests working from within companies, I feel laws and regulations are better suited to get a fair & transparent outcome.
The German model that the sibling comment brought up is quite sane in comparison. It limits the stakeholders to only those who actively participate in production, which provides a kind of decentralization enforced by laws, but not directly steered by central interests. In terms of overall benefit to society, it's hard to argue against that model and it has served the Germans well. (However, it's also worth noting that having unions sit on the board doesn't prevent the company from making unfavorable decisions outside of the limited national and workplace-environment-related interest of the extra stakeholders, and often those changes can only be deferred / slowed down but not outright avoided.)
