Since when do you need someones consent to say a thing about them?

You don’t need someone’s consent to say a thing about them.

But they clearly want to tell them, so why are they trying to do it in the middle of the night in a hurry rather than doing it calmly?

Why this self-imposed rush?

Nobel winners are all over the world, regardless of when you pick, there will always be a chance it's "the middle of the night" for someone. With the current time slot that happens to be for people in the US.

They could pick a slot that's during the day in the US, but then it'd be night for someone else. What justifies the US importance to make such a change? Using the timezone of the committee as they do now seems as reasonable a compromise as any...

But why does it need to be done at a single moment? Why not take a day or week to make sure you’ve got in touch with people? There’s no rush except what they create for themselves.
