My guess is Indiana likes the revenue bump from Chicago et al and may not want to push it. They do charge more for out of state entry and annual passes, which they could tweak.
I'm sure that's it, but they sure dono't hesitate to push it when collecting fees and taxes to residents

I'd probably be less cranky about, except for two things
1] Like Florida, the "no vacancy" sign goes up very soon at most parks. Certainly, more Hoosiers are camping, that is everywhere. I'd just love a system where as a tax payer who is paying the lions share of the parks upkeep that I get a slight advantage when booking. Florida is doing this now, giving residents a greater window.
2] When the great unpleasantness occurred, Indiana opened its sites up early compared to Michigan and Illinois. When I got to a park, the majority of license plates were from those neighboring states.
I'm probably at the core of this lamenting a decade ago when on a Monday you could probably find a site for the next weekend. Maybe not at the park you wanted, nor a particularly good site but you could find something.
