I keep thinking: this is what eg Google has done all along. The content it uses to train models and present the answers to us absolutely belongs to others, but you try get any content (eg maps data) out of it for free at scale.

But the business model emerged and delivered value to us while enough that we didn’t consider asking for money for our content. We like being searched and linked to. Less so Google snippets presented to users without the users landing on our site. Even less so generated without any interaction. But it’s all still all our content.
