I think most people would interpret free will to mean something that is perfectly compatible with any definition of determinism.
If I decide to raise my right hand, I raise it. Don't get pedantic in regards to disabled people. It doesn't matter if the universe is completely deterministic, that doesn't mean that I'm not the entity that decided to raise my right hand. The deterministic universe may have produced me, but the software I'm running is me. The reason I raised my hand is because of me. Sure there are an infinite number of factors that have fed into the circumstances of my birth, and everything that's happened to me, but everything that I do is specifically as a consequence of my free will. I am the software, deterministic or not.
