They don't do that now, but it's perfectly within their rights to do so if politics takes a hard left.

Of course the government could tax him heavily - that’s not the question at hand.

Yes, it's the shareholders business for they own the company.

That’s why I said “beyond those who own it?”

Theoretically, no. But look what a beautiful thread is on HN. Religion has thought mere mortals to be interested in the life of gods.
