The thing is, most of the contradictions between TCW and the Multimedia Project are not even Filoni’s fault, but Lucas’ fault. TCW was Lucas’ pet project, he had complete creative control over it, and decided whatever something was good enough as to be shown in the series, or not. He decided everything, so he’s the only responsible for the contradictions between TCW and the EU.
I don’t think anyone is disputing that George was in overall charge of The Clone Wars (the early seasons), or that most of the early contradictions in it likely came from George, or that it is likely that more came from George, than did from Filoni. But it does appear George did not have “complete creative control” or that “He decided everything”, and so on.
George actually wanted to kill Ahsoka off, Filoni didn’t, and so Ahsoka lived. That is quite a big creative control decision:

But I do respect your viewpoint, and I can see where you are coming from in the rest of your interesting post.
