Many philosophers are confused. Free will is a solved problem (we have free will regardless of the metaphysical premise, unless you're using a weird definition of free will, and even I can prove it for any given metaphysical premise), yet they're still working on it.

If somebody links "free will" to "determinism", they're very confused about what free will is.

There are a lot of philosophers doing genuinely useful work, but so much of the field is pre-occupied with trivial (and non-trivial) variations of the "if a tree falls in a forest, does it make a sound?" koan.
