The LLMs don’t deserve or have any rights. They’re a tool that people can use. Just like reference material, spellcheckers, asset libraries or whatever else creatives use. As long as they don’t actually violate copyright in the classical sense of just copy pasting stuff the product people generate using them is probably as (un)original as a lot of art out there. And collages can be transformative enough to qualify for copyright.
Of course they calculate quite well if it is worth the effort to get rid of fake reviews. I definitely think that they are something that Amazon would eradicate right now if they could do so easily. So as the quantity and quality of fake reviews is bound to rise with recent technological developments, the scales might tip into the direction of them having to do more about it. Because offering good deals as apology is not something that they’d be happy to do for more and more people.
Because nobody wants to sell this?
