Diversified shareholders. People who have much more of an interest in society than Twitter.

Nope, you could have zero interest in society, hold 51% of Twitter shares and own Twitter.

Please, this is Companies 101.

I'm not following you. I didn't take "Companies 101."

Nobody has zero interest in society, unless they are a rogue AI that isn't programmed to believe in physical reality at all.

Also, nobody owns 51% of Twitter stock.
