I'm not taking sides here, just adding food for thought.
The scraping of existing work, be it art, science, coding or literature, isn't the hill to make your stand on. Stephen King learnt to read and write by (essentially) scraping knowledge from people before him. I don't know in Mr King's case, but a lot of creators will say they were influenced by other people. The problem that will need addressing in the near future is precisely replicating existing works.
Two real world examples.
There are AI voice changers using famous singers. My son sent me a track he was working on, saying that Taylor Swift had emailed him begging to do the vocals. He even sent a sample. It was, indeed, Taylor Swift...AI Taylor Swift.
Mr Trump has been popping up all over social media in all sorts of places, poses and scenarios that the real Mr Trump would not be seen in.
Both of those examples are here, today. Both will fool the vast majority of people. How long will it be before lobbyists, lawyers, politicians, corporate HR etc. are caught proving that Mr Trump actually was drunk as a skunk on the number 77 bus singing like Taylor Swift. We have video proof. Here's a picture. We have audio.
Anyone can look at a painting and emulate the style, adding their own 'flair'. Anyone can read Mr King's novels and write about a possessed car. As long as they don't claim to be that actual someone, then that's acceptable. Why is AI any different?
I genuinely think that vandalising an LLM is rather petty and completely pointless. Anyone remember dual cassettes, VCRs, DRM, DVD burners, 3D printers. All of them were going to be the ruin of something.
