In Louisiana, you can hunt hogs at night most of the year. People here will usually keep and eat the small ones or sows, and won't eat a boar - they are nasty.
I do a lot of coon hunting, and the majority of those are left. If there is someone around who wants them to eat, I will take them some. But I don't eat them.
However, I go coon hunting on lots of very nice private lands, and the people are glad to see me and the dogs coming. With little to no fur market, coons are a varmint in lots of places. If no one hunts them they get bold. They get overpopulated and spread distemper. They are hard on wild bird populations etc.
Coon hunting with dogs can be a lot of work, and keeping just two dogs costs time and money, but I do get to make a lot of deer hunts because of getting to know people by helping them with their coon problem. And where I live, almost every deer lease has a coon problem. I really don't have time to go everywhere people ask me to.
Hogs are ten thousand times worse of a problem, and if you need to process every one killed, there is no way to kill enough of them.
I haven't seen anyone offering paid hog hunts, but I sure as heck wouldn't pay to hunt feral hogs.
