Personally, I would give it the escapee treatment, but of course an escapee wanted to be there while the human did not, which isn’t entirely the case here, but my opinions on captive/wild are a lot more liberal than a few others on the platform. I believe this situation is quite subjective and depends on the observer’s opinion. If iNat makes its stance clear on released animals (for rewilding/biocontrol or anything else) it would solve this problem and other debates that I’ve seen happen about similar situations in the forums.
