I didn't know this part about free will, and I have never considered any relation between Bell's inequalities and free will. The entire issue sounds even a bit weird in this context. Putting all of this together won't be similar to associate something microscopic with the free will of a human being, i.e. a macroscopic object to which the laws of quantum mechanics do not apply.

This being said, the role of consciousness (and the observer) in quantum mechanics is a very important question, and could also be associated with the design of a wave function for the universe itself. This leads to issues that are still unsolved today.
