I think that's a pretty wild statement: there isn't just one type of content!
Twilight fan fiction? Claude probably won't pay for that.
But critical programming documentation that its bots (and their human users) rely on to do their daily job ? You better believe Anthropic will pay for that (instead of letting another AI pay for it, and steal all their customers).
Sure, they'll probably pay PyPi, the Swift Foundation, etc for that documentation - but it's a pretty small universe of relevant content. An interns tech blog with a 'hello world in javascript' post won't be paid for, the Mercor contractors are doing more (and better) than that!
