How about the article you're commenting on? It said exactly the same thing, just different words.
In the end, those decisions, even if they were possible, would not be free will, but either arbitrary (random) or requiring some homunculus doing the thinking somewhere inside us.
Rather, I say, our will, and that's free enough, and as free as it gets, is mixed up in ourself: it is ourself. Our body, past history, experiences, brain structure, etc, define us, and their sum is what ends up taking the decisions.
Thus it doesn't even matter if our "conscious self" is not aware of a decision we've made as some studies say [1]. Our body is still us (in fact, that's all there is when we talk about our self, our body + our neural synapses as shaped by our life experiences from our trajectory in space-time). We are not some souls independent of our body/life story. We ARE our life story/body.
This means that determinism (that the universe makes us takes exactly a specific decision at every point etc), if exists, is totally combatible with such a notion of free will. Free doesn't mean "able to go random" but "expressing freely its owner" -- and since our will's owner is our body+history, it cannot but take a single decision each time, those that determine who we are, and thus our essence.
