I am perfectly entitled to type random stuff into google images, pick out images for a mood board and some as reference, regardless of their copyright status, thank you.

It’s what every artist does, it’s perfectly legal, and what those models do is actually even less infringing because they’re not directly looking at your picture of a giraffe and my picture of a zebra when drawing a zebra-striped giraffe, they’re doing it from memory. At least in the text2img case img2img is a different matter.
