Vettel wasn't moaning about being overtaken. He was moaning about being held up by a HRT so much that Hamilton got a run on him.
Point being where would Hamilton have been anyway if he wasn't held up almost a second a lap before, and where was Vettel when Hamilton got held up by half a second in sector 1 a few laps after he over took Vettel.
Hamilton was on him, gaining, sure the HRT helped him overtake that lap, but he was gaining, it was coming anyway and overall Hamilton was hurt by back markers more than he was helped throughout the race(okay probably, seemed that way).
The main thing was what Hamilton said, he could see the back marker coming up, he could see that this was his best chance, he turned the engine up and stormed through sector 1 anyway, and he was faster in sector 1 by a large margin normally. Why didn't Vettel see it coming, look at the final lap of the race, if he could see an HRT coming up, turn the engine up for a lap and make sure you don't get caught in S1 behind him. Why didn't he see Hamilton's delay behind a backmarker coming and take advantage himself.
Overall he just sounds like a whiny ****.... considering the speed Vettel could put in on that final lap and closed almost a second on Hamilton in one lap, why wasn't he doing that for a few laps after being over taken?
Also they didn't explain it all, it was there INTERPRETATION of why he was angry about the over take. He quite clearly on the radio complained about Hamilton being far too close when he over took, and he seemed to neglect to mention he took a little swipe at him which caused them to be that close.
