You misunderstood me there a bit.
The likening to a photographer or photoshop wizard goes more in the direction of what an AI user actually does, giving importance that it still is a person using an advanced tool. And those activities and their results are established and not stigmatized nor banned for the tools used.
And the discussion if and what kind of consent is necessary to use material to train an AI with, is not finished*. Especially because the discussion about AI bans and stigmas will flame up anew, if tools emerge that indeed only were trained with training material that was ethically aquired. Also, if you ban those, you would have to ban a lot of other stuff for similar ethical reasons. It is a can of worms. The only thing quite clear is, that it is not ok to use those tools for plagiarization and defamation and similar. But this is because of what you do, and not how you did it. It is not ok to create such works with photoshop either.
So my point is what I wrote. It is necessary to wait for actual legal stuff and not perceived ethical reasons. Ethics are quite fuzzy and subject to change a lot and are very, very arbitrary. For example, it is unethical in my opinion to outsource jobs into other countries and exploit work conditions there. Same for several and most tax evasion maneuvers and lots of other despicable stuff that Harvard would be proud to teach students. Do you boycott and ban any and all companies that engage in such unethical activities? Yet here you call for ban of things for ethical reasons. I say, ethics is not enough.
But rest assured, AI games already have stigma. There are enough haters, and haters they are, that downvote such games. And I do not believe for a second, that those haters will upvote games that used ethical AI stuff.
* My current stance would be, that if it is ok to look at a thing, it would be ok to train an AI with it, if the AI does not copy the thing, but extract the essence. Or in other words: learn. Quite like a person would learn from being "trained" by studying other peoples art. Just look at google image search. That pattern recognition system is an AI in my book. It is used more to recognize and find things, not to randomly create things, but effectifly it was trained by stuff without giving consent for AI training.
