As Sasaki went into, it is Semantics.

Define free will.

Is having predictable behaviour classed as free will? such as, you enjoy pepperoni pizza, therefore if I gave you pepperoni pizza, I predict you would enjoy it, and when I gave it you, you did.

As well as personalised tastes, people follow rituals. People generally do the same things all the time, we are creatures of habit. You don't suddenly randomly put on a pink dress and walk out the door just because you chose to, though given circumstances and your behaviour patterns, you might.

Hypothetically speaking, if I had all the data to how you would respond to something, I could hypothetically tell you your entire life story and how you would react in certain situations. Does this mean you process no free-will? No freedom to make a choice?

Answer is, you do have the freedom to pick up that pizza and eat it or not, however, behaviour is inherently predictable given if you know a certain about of information about a person, so I could predict what you would freely choose.
