This whole AI scraping argument is so silly to me. If you don't want people downloading and processing your content, then don't post it on the public internet?
They literally outline their reasoning in a link[0]. There’s a significant gap between offering information for someone to read for free (where I can see the author and choose to respect their terms, if they have any), and a huge tech company aggregating that data where it is assimilated into a model and used in a product they will profit from[1]. They are exploiting gray area regarding digital rights, copyright, etc.
It's not about not wanting people to access the content, it's about not wanting AI bots to do so. But yes, I agree, the only realistic defense we have is to remove it from the publicly-accessible web.
