Product descriptions are a good example of info that will still be published, because people will still by buying and selling products. The problem is with writing where the writing itself is the product, such as news.

The LLM relies on free access to that writing in order for it to be informed about current events. The news publisher relies on readership to pay writers. If LLMs are too useful to the point that people rely on them alone for news, then ironically they will become worse products over time as the publications they draw from go out of business.
