This is not at all how share ownership works. You don’t have partial title to a corporation by owning shares.

Shareholders functionally own the company. Yeah you can't stroll inside and take a ream of copy paper because you own a few shares, but the company also cannot be sold (ownership transfered) without you getting paid for your slice.

The shareholders, via the board, hold final say over the company, it's direction, and it's alignment...because they own it.
