The most important thing is to acknowledge that "freedom of choice" or "free will" or any concept like that isn't a binary. Addiction and marketing both prove beyond a shadow of a doubt that we don't have "perfect" free will, and this is both (1) true regardless of what you think about determinism and (2) more relevant than any consequences of whether the universe is deterministic or not. The pragmatically relevant aspect of "free will" is to what extent our actions can be predicted and/or manipulated by others today and in the future. This necessarily involves e.g. measurement and computational limitations that others have, and it's something that occurs on a scale rather than as a binary.
