Sure and that's one way to solve royalties.

I suspect from purely logistics, AI training is better when it's free to injest all the content it can, and for that freedom it pays in some small royalty amount when that source is cited.

They'd simply pass that cost onto the customer. For universities or enterprises or lawfirms, or whatever, they would either include pre-existing agreements, or pay for blanket access. Whatever terms OpenAI, Anthropic, and Gemini sign with these entities, they can workout the royalties there.

These are all solved problems for every other technology middle man company.
