We do not have free will.

"the power of acting without the constraint of necessity or fate; the ability to act at one's own discretion."

That's not necessarily unbound. It's not talking about the ability to literally do anything. You are always constrained by the laws of physics. I don't have the free will to fly off. I don't have the free will to breathe in space. However, I am not constrained by "fate." I have discretion. Now, that discretion may be constrained by my personal mental issues from how I was raised and my life experiences to some extent, but that's neither necessity nor fate.

Research also shows that we retain veto power over a decision. Again, the part that might illusory is the idea that we are a single whole entity as opposed to a series of sub entities making collective decisions and presenting them (and yes even starting them in some simple cases because the dangers of life require faster movement in the physical space) but given the "executive I" the chance to override.

Which happens all of the time. You start to reach for something or step in a direction and then you think, wait a minute, no I don't want that or to do that or whatnot and you change direction.

And nothing about that suggests anything about much more complicated or deeper thoughts that don't involve something as massively simple as "lift your arm." That could be nothing more than efficiency of use of limited brain power. There's no need to involve the "boss" in every single little action. Imagine how distracted you would be if you literally had to think about moving your legs for each step. Every single fine motor action. The processing power your executive conscious would have to use. You'd never get anything more complicated done.

I think you are reading a lot into a single study.
