Transformers NY

I heard on several articles about the bouts she had with the director while directing for Transformers 2:Revenge of the Fallen, so when the 3 Movie came in play, she seemed to still have some conflict with the director, so she was booted from the cast.
Does anybody else think otherwise? And if you put an answer, like it was because of the abortion, please link an actual news link so I can see some legitimate proof that your thoughts are true and not just opinionated.
