I understand why you would call your offer a free choice, the are no constraints attached to the options that could obviously influence the decision, for example picking the ice cream also requires paying a million. Different people with different preferences would make different choices. But pick one specific person, why would you call their pick a free choice? There choice might not be influenced by your offer but it will be by their preferences. Let them choose, rewind the universe a minute or two, let them choose again. They will make the same choice over and over and over again. Maybe not if there is true randomness in the universe and this choice happens to be influenced by some random event.
