one and only time i will  comment on the subject..... a very hard nut to crack....from what i have read on the subject....

LAION-5B: An open large-scale dataset for training next generation image-text models...was as far as i'm aware....reviewed by a extensive group of AI ethics researchers..on a academic and scientific level before its release date,

AI art models "do not store com­pressed copies of [copyright-protected] train­ing images” and then “recombine” them; functioning as “21st-cen­tury col­lage tool[s]  AI art models do not store images at all, but rather mathematical representations of patterns collected from these images. The software does not piece together bits of images in the form of a collage, either, but creates pictures from scratch based on these mathematical representations/ approximation...if it was as individuals suggest using images...then it would be a perfect reconstruction, or reproduction....so common sense and logic say its Computer Pattern Recognition....

Copyright law protects finished works of art. It does not protect things like facts, ideas, procedures, or an artist’s style, no matter how distinct. there is no country in the world that copyright law covers an artist style, artistic techniques, artistic genres, or art movements....

There is also that Fair use....doctrine in United States law that permits limited use of copyrighted material without having to first acquire permission from the copyright.....

"The law of copyright is clear that only specific expressions of an idea may be copyrighted, that other parties may copy that idea, but that other parties may not copy that specific expression of the idea or portions thereof. For example, Picasso may be entitled to a copyright on his portrait of three women painted in his Cubist motif. Any artist, however, may paint a picture of any subject in the Cubist motif, including a portrait of three women, and not violate Picasso's copyright so long as the second artist does not substantially copy Picasso's specific expression of his idea."

It's a minefield that will go on for a very long time....and will have no clear cut outcome, unless they can prove it categorically one way or the other...without any gray areas.....
