Well it does, but it requires a number of assumptions that are not required. It has to do with actions done under omniscience and it also assumes that actions retain omniscience.
Assume Free Will. Person A is free to choose between option 1 and option 2. Person A can only make one choice, from a static universe point of view that choice is known.
Let's call Omniscient Being OB.
OB therefore knows what option would be chosen given no interference. OB then places an event before the choice that changes the probabilities. OB then knows the resulting choice.
OB then continues to do this until the event changes the result of the choice is the opposite of the choice without the interference.
Is this still Free Will or is this an illusion of Free Will.
Note the assumption; it assumes that all changes are made with the explicit understanding of using omniscience. It is clearly possible to make all actions without using the omniscience you already have. It is also possible that you can impose the notion of singular interference, so that at the point of interference you don't know what the result would be because it has not happened yet and thus cannot be observed.
So the straw men (in other words the hidden false assumptions) are easily revealed.
