I would've thought that the difference between "vote" and "vote as a shareholder" would have been obvious enough, but just to make it clear: I don't consider it a good thing if the only people with a say in things are the ones who have money. This is the difference between a democracy and a corporation.
I find it really unsettling how many people on HN seem to need this distinction explained.
I doubt Uber is going to hire you if your goal is to change its business policies. Voting as a shareholder is also not the same as voting as a citizen. Everyone has the right to vote as a citizen, only the right h shareholders in Uber have the right to vote as a shareholder.
Additionally, the problems like gerrymandering still appear in different forms in corporate structures. Often times founders have majority control of the company in the form of different shares. While this is good for the founders, this is bad for anyone else who doesn't like the direction of the company.
You can do ALL of those things with uber. You can vote as a shareholder, apply for a job, petition, volunteer, protest, etc...
