> A search engine index is an economic exchange between the website and the publisher.

A search engine index is a search engine index. It can have an economic impact, but it can not be an economic exchange, since it is a technical artifact.

Though I think I understand what you are trying to say - this is also a commercial relationship where both sides can profit. You are free to interpret the relationship between publishers and search engines with such a capitalist lense, that does not mean those mechanisms govern the actual rules. That a publisher is happy with what happens here is of no real concern. If any rules apply we are talking copyright, maybe media law, where happy is not a relevant category (ok, that of course can matter, it wouldn't here if the search engine uses a right).

I did not touch the LLM training data in my comment, as I did not read up on what Brave is really doing there. If Brave were really to sell complete texts from others, that would not be legal under copyright laws I'm familiar with, so I kinda doubt they do that.
