If he earned them, then why did he all of a sudden stop earning them after Turkey? He had 7 podiums in a row, 5 of which were wins, then didn't get another podium for 6 races. Qualifying followed a similar pattern, while the rest of the teams were trying to catch up on the diffuser tricks he was getting pole positions left and right, but after Turkey, well he got a 3rd in Germany but nothing else too impressive.
The other drivers didn't suddenly wake up and say "Oh Christ, I'm racing aren't I?", it's pretty clear he had a superior car to start with, then couldn't manage to keep up in the mid and late season once everything had settled into place so far as relative car performance.
Jenson is good, no doubt, but he's really only capable of winning when all the cards are stacked in his favor. When the car became less than perfect in the mid-season all you heard on his team radio was an incessant whine, unlike Rubens who was able to pick up two wins. He's only good though, not great; likewise he did deserve the championship the most out of anyone on the field this year, but that's not to say that he deserved it as much as other champions who were strong contenders all year long.
