I actually don't think this is true. I think most people don't even recognize the existence of the universal will to begin with. Their belief in free will (unlike yours) isn't based on a nuanced consideration of other, contextually practical, definitions of free will, but rather on a failure to address the cognitive dissonance inherent in believing that every person constitutes a separate eternal axiom of the universe, in addition to all the other eternal laws of the universe.

In other words, most people's belief in free will is based on intellectual laziness, more than anything else - even if there are ways to conceive of free will that aren't intellectually lazy, and even if those other conceptions are similar in practice to the lazy ones.

But I think it is important to start with an acknowledgment of the universal will, as you did a couple sentences before the one I highlighted here. And it's important to keep that as our base. Because although there may be other perspectives, the other perspectives are all necessarily biased or arbitrary in some way.

When we say that someone had free will in a given context, what it usually means is simply that we don't have enough information to predict what they will do next. We presume that 99% of people who wake up tied to their bed will struggle against their bonds, and so it doesn't seem like a choice. And the situation would be similar if someone were acting under fear of some threat or blackmail or other coercion. The coercion makes their actions predictable.

And that's really all it comes down to. If we don't feel we can predict the choice, then we call it free will. And if we do, we call it "unfree".

But the problem is, a lot of times, the difference between predicting someone's choices or not just comes down to how willing we are to try to understand, or empathize with, people.

And that's the real problem with free will. It's that it gives people a vector for projecting their biases onto people's successes and failures. That's why some people love and adore Elon Musk for his work ethic, while other people say he's just a spoiled brat.

But both interpretations are just projections, where some people choose to believe it's his "free will" that makes him successful, with his personality being just a predictable byproduct of his success, while other people choose to believe that it’s his "free will" that makes him a jerk, with his success being just a predictable outcome of his parents owning a diamond mine.
