Randomness doesn’t really save traditional free will. A robot that selects its actions by rolling dice is not any more “free to choose” than a robot that selects its actions according to a deterministic program. There isn’t any free-will juice that gets introduced by adding randomness.
Your “free will” is the process by which you select actions. For humans, that’s a bunch of physics and chemistry happening in your brain; it receives influences from your senses, your body, and its own self-awareness (i.e. its model of you, your actions, tendencies, etc.). Whether that process depends closely on QM, or is boringly classical, doesn’t control how “self-determined” it is.
