Hot on the heels of Sunday's other controversy about the Red Bull's engine software, the team broke the post-race drive-through penalty news with a statement entitled 'Never a dull moment".
McLaren's Button, who is promoted from third to second, called the stewards' decision "straightforward".
"The rules state that you can't go off the track to gain an advantage," he said.
German Vettel and his boss Christian Horner tried to argue the case, but Button insisted: "There's nothing to say really, I think the TV cameras say it all."
The TV cameras also captured Vettel describing as "stupid" Lewis Hamilton's decision to overtake him, despite being lapped.
"That was not nice of him," said the German. "It's a bit stupid to disturb the leaders. I think that potentially lost us the position to Jenson."
