What if the website does add value to the LLM, but only in the training/indexing stage? Like, if I create a website that painstakingly measures and lists the weights of thousands of widgets, then the LLM ingests that knowledge and then never sends the user to my page.

Maybe it's more convenient for the user to pay the LLM for the info (paid via ad attention or whatever), but if I'm the one who made the measurements, then shouldn't I be paid too? If the user never "pays" me, then I'm going to stop publishing measurements, and the whole LLM falls apart.

Likewise for generative art. The people who made the training data are a critical part of the ecosystem. Cutting them out seems like cutting out some critical part of a food chain.
