Whatever the case, the stewards gave Hamilton a reprimand. Why else would the give it to him unless the felt he played a part in the accident? They clearly felt that Hamilton, perhaps unintentionally, provoked Maldonado, and it was that provocation that led to a) the reprimand for Hamilton and b) a lesser penalty for Maldonado. People dislike Maldonado for what happened, but the fact that Hamilton was reprimanded means that the stewards have evidence that he did something and Maldonado wasn't entirely to blame. Personally, I believe that Hamilton mistimed his run, and squeezed Maldonado wide coming out of the Bus Stop because Hamilton knew he was only going to get one run. On a drying track, Maldonado stood a real chance of improving both his lap time and his qualifying position. But because Hamilton was aggressive through the chicane, Maldonado lost out, and five hundred metres later, he vented his frustrations at Hamilton. If Hamilton did not force Maldonado wide and failed to reach Q3 as a result, then that's Hamilton's problem. Nowhere is it written that Maldonado had to let Hamilton through.
As for the account of what happened, I'm not making things up. I'm simply going off the Wikipedia page, which appears to have the official version of events. That might not sound like the greatest source, but the Formula 1 editors are pretty rigorous over there. Especially for something as controversial as this collision.
