Why Did Lewis Hamilton Lose the Race?

The race director had two options. One was to follow the rules and let the race end under the safety car, in which case hamilton would have won. The second option was spice things up, you know, change the rules a little bit and restart the race for one final lap. It gave him a chance to go change his tires and then pull ahead and win. So that's why lewis hamilton's fans are pissed at what happened.
