Not sure where the Lewis made an illegal move is coming from, but there were other and more egregious moves during the GP so that you point at that, you must understand why someone would question the motivation. IMO, I thoroughly enjoyed seeing a race free of accidents and boneheaded moves and most importantly free of arbitrary and often patronizingly handed down penalties.
The motivation is that someone previously in this thread posted a rather silly comment, unprovoked as far as I noticed, criticising unknown and unnamed persons who were criticising Hamilton for weaving when that's just "breaking the tow". Look for my first post, then just above it. Hence I followed up showing that it there is actually gold plated evidence of Hamilton's moves being against the rules. By posting a link to the video, specifying the exact seconds to watch, and then quoting the relevant rules.
Defending a driver is one thing, but defending a driver when there's unmistakeable video evidence that they're in the wrong. Well, that's just silly.
And defending a driver because someone else apparently did something worse. Even if this did happen (has anyone posted the example yet?), it doesn't excuse anything Hamilton did.
