I don't think he is the wrong champion. I think that Vettel and Red Bull fully deserve the driver's title, which they achieved together. Had McLaren performed at the same level or had Ferrari produced a better car then we could say that Alonso/Ferrari deserved it or Hamilton/McLaren deserved it... but they didn't. Based on all facets of driver and team performance it is absolutely right that Vettel won the driver's title with his team.
