There is no absolute proof the incident was intentional, that is why 8 hours of deliberation were necessary; I feel the decision was a bit harsh, given the circumstances, and a better resolution might have simply been to take away his three fastest times, as they did to Fisi for holding up Coulthard.
Regardless the race itself showed Michael is still an awesome competitor, and a force in F1, as he started from the pit lane and worked his way up to 4th on a track that is a PITA to overtake on, in cars that are not ideal for overtaking - the F-car and Shumi haters will jump on anything they can in an effort to attack this guy, when there is a very real possibility he simply made a driver error (those do still happen, even in F1) - also note Massa crashed out his Ferrari after visible traction problems, and Michael locked up going into the corner - if the car was a handful a driver error is even more possible, but instead he gets sent to the back of the grid.
Even if the event were intentional, which there is no absolute evidence of, there have been many drivers in formula 1 who were just as ruthless in their pursuit of victory, Senna being a notable world champion, famous for the same actions everyone attacks Shumi for.
