I'm not exactly disagreeing. I'd absolutely explicitly dump my Amazon (the whole mutual fund its in actually) if a robot-owning stock with a "shareholder bill of rights" as you describe existed.

A product/brand independent "means of production" type investment is an interesting idea. It still doesn't fix the fact that there are people who are just never going to have the resources to buy into such a thing, which I think is really the core of the issue.
