The racing line for the corner in question isn't the line that Hamilton took.

Hamilton was right up against the white line on the exit, giving Maldonado no choice but to go off-track. Maldonado was marginally ahead in the braking zone, making them wheel to wheel on turn in.
Pause at 0:04 to see that Maldonado is ahead, but Hamilton had the corner.
Pause at 0:06-0:07 to see that Hamilton squeezed Maldonado off the track.
Pause at 0:08 to see that Maldonado begins to turn left but the floor is on the kerb and he goes straight on into Hamilton.
No question, it was Maldonado's fault ultimately. But to say that Hamilton was blameless is idiotic. He wasn't on the usual racing line, he squeezed Maldonado off the track by going wide instead of leaving room as is not only the normal racing line in this corner, but also the etiquette for wheel to wheel racing (Which Hamilton did excellently with Webber last year in Korea). Here he drove Maldonado straight off the track, after blocking him at the beginning of the preceding straight (Which the BBC footage conveniently doesn't show on the replay, instead it shows a wall - I will post up when the full race footage is available if anybody likes)
