It's flawed to think an artist referencing others to produce their original is the same as an AI-Artist stealing artwork to generate an original. Youtube, Facebook, TikTok reciprocates value to its customers in exchange for selling their data to advertisers.
What value are YOU, the AI-Artist, providing the artist for their data?
Note: I'm ignorant in this area. My views are based on personal conversations with how influencer artists' feel about this popular trend.
