There is so much nuance in something like this. Hunting an animal that was bred and raised for the lone reason of being released, to shortly thereafter be hunted, will get the side eye from the vast majority of people. Make it a lion; one of the most epic, old Africa hunts imaginable, and that gives off a vibe of dangerous game larping (even if the actual danger is still there). Like Commodus acting out a choreographed sword fight at the beginning of Gladiator. It really is the perfect storm to garner hate from all angles.
A close example would be a post I read a few years back. A guy had a complaint about a deer breeder. He'd purchased some stocker bucks to be released into a small high fence so he and two buddies could hunt them. I forget what his complaint was about the breeding facility, but he was surprised when everyone disregarded his complaint and was laughing at him for having deer delivered just to hunt them in a small enclosure. Different animal, same result, different type of outrage.
