Reading it again in context, your response is at best completely misunderstanding what is being said.
They are not “insulting indie developers by insinuating they’re not real devs and have no right to exist.”. They are saying that developers who rely on AI models should compensate the artists whose works trained that model. The model itself can only exist through processing artists’ copyrighted works.
As much as you talk of defending the little guy from corporate dominance, it doesn’t seem like you are considering the position of game artists, or any other small artists.
Just as that article does, frankly. Not only it seems entirely unconcerned with the realities of artists in a world where AI can replace them, its defense of scraping as “analytical” doesn’t seem very sound when the entire purpose is to create derivative works. Lets not forget that law exists, ideally, to protect people. Any argument that alteration to the law would make it worse tends to treat AI as equivalent to human, which it is not and it shouldn’t be treated as such.
