Read it again.<quoted text>
Yeah, he wasn't talking about control, he was talking about simply knowing. If you know the future, it becomes set, thus, your god has eliminated "free-will" simply by knowing the future.
He said something all-powerful, "by definition", is in control of everything.
Your view of free-will and foreknowledge is simply wrong. It is the choice that determines the foreknowledge, not vice-versa. Time would not be linear to an all-knowing entity. If the choice were different, the foreknowledge would be different.
