Blackrock and Vanguard don't own everything. While Blackrock does directly control some assets, Vanguard doesn't. They have a large amount of assets under management, which means they manage assets for other people. If all of Vanguard's clients removed their money, vanguard's assets would be a few buildings in Malvern, PA. Even their votes on the board are because they are proxy voters for the actual owners (the clients), and most people just don't exercise their right to vote on things.
