I second this. In my comment this is why I wanted to ask more about what’s meant by “observer” in the definition. An individual mind/perspective (regardless of computational power) being able to predict action is different than “predictability” by theoretical simulations of the universe.
That said, if we do define free will as predictability by a fellow human observer, then we could absolutely have free will of that type. We don’t even really need proof of that, we can just observe the plethora of evidence that people do not often perfectly predict each others actions.
