They do have it. But people do not give a single crap and don't use it. I seen only one who did so far, and they used it for coding and stated it clearly, which I wholeheartedly appreciate.
I know. I am an artist myself, and I can see almost all the time what is ai and what isn't. But I do not understand why people cannot be just transparent with either they used it or not. Especially when they sell ai crap to people.
