It’s like the search summary problem, only worse. Before, people lost traffic already cause Google would try to answer the question with a snippet from your site; however, LLMs (or at least ChatGPT) are trained on Wikipedia, because it’s available data. With Reddit being first, Wikipedia being the second largest source of facts they used (at least, according to statista).

Side note, you’re not even supposed to source facts from Reddit or Wikipedia, they’re better for finding other sources. It’s like a game of telephone, at the tertiary source you’re getting even less accurate information. It’s just oh so stupid the direction end users are herded towards.
