You might as well ask why people bother asking it questions or talking to it at all on that basis. The fact it does typically respond differently to commands than to questions is part of the power of how LLMs work (whether that's entirely due to the fact its training data includes examples of commands being given and appropriate responses or it's explicitly part of the programming I couldn't venture to say, though I suspect the former).
