Selling generative artwork from Adobe Stock then re-created as match style in Adobe Firefly

I believe that clause  is also intended to prohibit you from trying to mimic graphics and characters from app-based games. 

There is a command (it may be different in different AI applications) called 'describe' or something similar, wherein you take an image acquired from wherever and it will generate random prompts based on that image. I've used it numerous times by submitting my own photographs (that is, real photos I took years ago) to generate prompts. The resulting prompts have always bore little to no resemblance to my originals stylistically, especially if I use different aspect ratios, change black and white to color, change the nationality of the subject, or the environment, the type of clothing, etc.

This method often results in the prompts including the names of other photographers or artists (are THEY stealing MY style?), which I then remove or even replace with my OWN name (although I guess I'm not famous enough for the results to have any bearing whatsoever to my own photographic style, as my images are apparently not included in the database of the AI apps in question).

That said, I have experimented with using prompts such as "award winning Time magazine cover," which scarily resulted in near replicas of same. Those get assigned to the trash immediately and I never use "award winning photo" under any circumstances, which is the closet thing to actually including someone's name.

In the end, you just have to question if the results fall morally or ethically within acceptable boundaries without infriging on the rights of others. Experimenting is encouraged, but know where to draw the line and don't cross it.

1. you can't copy the look and feel of something. So you can't copy, just as an example, pac man, or an iPhone or similar. What you create should be genuinely yours.

2. You could take pictures of yours. If you take something from a different person, you may or you may not infringe that person's rights. 

You can't hardly get something more crystal clear than what you find in the documentation. If would suggest you search for the webinars of Mat Hayward and other Adobe people on this. They give additional guidance in the webinars.
