I don't see why anyone should accept a useless definition as a correct one. Nobody would argue that they had free will if they didn't feel like they had free will. Nobody is positing baseless metaphysical nonsense without some reverence in their actual experiences. If you want to usefully discuss free will, you have to account for the sensation of free will, not just some abstract model that you've merely assembled grammatical statements from.
