I'm assuming that this camp views legal responsibility for one's actions as being totally unrelated to free will.

That sort of free will is not compatible with a deterministic universe.
What makes "free will" free to the compatibilist?
Paul used to be a slave. However, he was granted his freedom and is no longer a slave. That makes Paul a free man.
Imagine, following this, that someone would say: "Well, of course not! Paul isn't free. After all, he can't just jump up and fly like a bird. He can't defy gravity. He can't make logical contradictions true. Paul is not free at all!"
How would we react to that? I think we'd tell that person that they're just being silly: clearly that's not what was entailed by the suggestion that Paul is free. Rather, we meant that Paul has some sort of political freedom. He is free from slavery, and enjoys a certain freedom from coercion, external determination, etc. In other words, he is free to the extent necessary to enjoy his personal autonomy.
The compatibilist is saying a bit the same thing. When we say "free will", we're talking about free to the extent necessary to be morally responsible for our actions. Now, of course, it may be that nothing short of acausal, indeterministic choices allow us to be morally responsible. In that case, the incompatibilist would be right. However, it's a question we need to ask, and we can certainly not presume that incompabilism is right; we have to argue for it.
Presuming incompatibilism is true while believing in determinism would be rather circular, since what is a stake here is moral responsibility: by presuming both true, we're basically positing that it is true that we don't have that thing which we need for moral responsibility, and from that we infer that there is no such thing as moral responsibility.
There is a strong sense in which compatibilists are very likely right about what the word free means in free will. They're likely right (I say "likely" to make room for positions like Fischer's semi-compatibilism) that we're talking about specific kind of freedom which is necessary for moral responsibility. That said, this position doesn't mean compatibilists are right about free will being compatible with determinism. Incompatibilists may still be right, because it may be that the proper extent of freedom of the will required for moral responsibility is something that isn't compatible with determinism. However, it's very much not just a question of semantics: it's a substantial argument about which level of freedom is required for moral responsibility, and incompatibilists that engage academically in the debate understand that. Those "good" incompatibilists understand the problem like the compatibilists: as an issue of framing exactly what is this freedom we need.
Daniel Maidment wrote:Dennet also bothered me in this, I've read some of his books to figure out just how exactly he manages to reconcile hard determinism and free will, and he doesn't end up managing. Only skirts around the definitions, which I think can be summarised succinctly as this:
Game Theory -->
1 player in the system --> simple system
2 players in the system --> attempt to out compete the other --> guess the others intent --> recursive guessing --> complexity --> effective free will because system is too complex
Reality -->
many players --> system is stupidly complex --> predicting outcomes is absurd --> might as well call it free will.
So yeah, Dennet's approach comes down to condescendingly saying that even if reality is perfectly causal, which would imply determinism, it doesn't matter because it's so complicated anyway. Which is a bit of a cop out. Don't get me wrong, I love Dennet and his work, and to a large degree I agree with him.
What's the best argument for free will you've ever heard?
Think about how the concept is employed in our everyday life. I am writing this of my own free-will. What is the purpose of saying that? Well, no one made me write this out, and I'm intentionally writing this out. The first mistake is to think the question 'what makes an act free' is a causal question, because it leads back to the Empiricist picture of 'the will', whereby 'acts of will' are posited as the causes of human action, these 'acts of will' are mental causes we bring about, which bring about acts which are free because their cause is free, however as Ryle noted, this leads to an infinite regress, since we must then explain whether that 'act of will' was itself free, and either its cause was free or not, if it was free, then we can again ask whether that cause was free, and so on.
The problem of 'free-will' is always couched in conversations about causality, but that, as far as I can tell, is very very far from its conception and use. If you go into the court system, you'll realize it's used there, extensively, to assign blame or to exculpate individuals for certain acts, or failures to act, because they were either coerced (someone put a gun to their family and told them they had to do such and such or their family would be killed or some such) or they were ignorant of some fact they couldn't reasonably be expected to conceive of (someone puts a bug in your salad and you ate the bug, but you were ignorant of doing so, you didn't freely eat that bug, and cannot be held responsible, instead, whoever put it their will be).
So to my eyes, free-will is an ethical concept, not a metaphysical concept about causality and agents who cause their behaviour. It's one of many concepts we use to characterize human life, others are psychological (where the concepts of aim, desire, intention all play a role), another is agency generally (where we have agents and patients, and we need to decide what the difference is between, say, you picking up your coffee cup and the beating of your heart), and then the concepts of reason (such as knowledge, ignorance, belief). All of these play a role in accounting for human life, but each is distinct. If free will is anything, it is a capacity to both act and undergo things free from ignorance and coercion. We say that someone was kissed, and that they accepted the kiss freely, so note that free-will is not used simply for actions done by agents, but also for actions received by patients, something passive can be received freely, as when someone offers to give me a back massage, and I freely accept it.
