I think the backlash isn’t necessarily against the decomp itself, but rather the sloppy/buggy PC ports that often come from it.
In my mind using an LLM to assist with decompiling is fine, as the output is provably correct. It either compiles to the original binary or it doesn’t.
Turning that into a playable PC game with controls that feel good, etc, is a different story. That requires human taste & judgement.
