The answer is that it's not okay and never was. Do you really think you're pulling a gotcha here?
Photoshopping nudes of your coworkers was always seen poorly and would get you fired if the right people heard about it. It's just that most people don't have the skill to do it so it never became a common enough issue for the zeitgeist to care.
I am not trying to pull a gotcha and I made no claim that it is okay or not okay. Don't suggest otherwise. I also wasn't talking about coworkers or any other particular group.
My argument is that it is either okay or not, regardless of the tools used.
Creating CSAM or non-consensual sexually explicit images of others in photoshop is immoral. If you can’t see that then you need to take an ethics course.
