Perhaps you were using a different version, but I just tried and ChatGPT didn't seem to have any ethical issues with the question (although it was cagey about giving any definite answer):
I wish more people would do this. I'm getting pretty sick of the walls of text.
It's absolutely ridiculous to expect the entire internet to adopt some kind of hygiene practices when it comes to text from GPT tools simply for the sake of making the training process slightly easier for a company that certainly should have the resources to solve the problem on their own.
If that's why you're using images instead of text you're fighting such a losing battle that it boggles my mind. Why even think about it?!
I saw someone on here refer to it as "listening to someone describe their dreams." I pretty much agree with that.
