HN has a higher proportion of AI promoters than AI skeptics, and for a good while, the default response to complaints from book authors, bloggers, and other content creators was that "you put it on the internet so it's fair game", or "it's no different from a human learning from your works". So yeah, unless we're willing to revise these answers, I think the same "tough luck" reasoning should apply here.
For folks who are at Anthropic, OpenAI, xAI, or Google, and think it's fundamentally different, I would ask you to think long and hard about that answer.
