The only one I can think of is, having a better idea of which way the presidential election goes might've been useful for some people, or some other large election. There's a lot of egg on the faces of all these mainstream media polls, which still continues to trigger some people.
So what happens when someone like musk spends a few hundred million to skew what the probability looks like? Suddenly people see that a politician has a 90% chance of winning, and they feel silly voting for the operation?
These are not polling places, they are places for capital to influence odds.
