Yes you are absolutely right. In this case it is about Tesla, owned by the richest man in the world. In other cases it has been about a salad bar run by an ordinary small-business owner. The "Swedish model" is that they should all sign collective agreements or else the unions will be very unhappy and you will have a hard time to continue running your business.
No single person owns Tesla. It's a publicly traded company, Elon does not have majority ownership nor control of the board. Anyone can buy shares and take ownership or run for the board.
