devils advocate: if it wasn't subscribers only, google's crawler would be stealing it right now to train an ai with, ie, illegally creating derivative works based on their articles
Maybe there's a market in the future for "AI-restricted" content. You can send your payment/tokens/etc. to access the content and the user is bound by a no-AI-clause. Because this content would be rare and can't be found via models, it offers a niche market.
I wanted to delete the other link, but hackernews doesn't allow me to do so.
Also, I need to figure out why the link is subscriber-only. It was not intentional.
