I don't think anyone is saying that Vettel wasn't a dick. But I think people are saying that if webber genuinely had the pace he should have protected himself. He isn't dumb, he knew Seb was coming for him.
This.
Vettel is a selfish arse and a childish brat who throws his toys out of the pram. Anyone winning other than him would have been a preferable result to most people, including me.
But he saw an opportunity to win, and took it, however "unsporting" it was. And at the end of the day, when we line the 24 best drivers in the world up on a grid and ask them to race, isn't that what we want to see?
