Correction: they're not their ads, but they're generating recommendations based on scraped web content which will inevitably be polluted with affiliate spam, astroturfing and other black hat marketing bullshit. They've actually found a way to run ads and not even get paid for it.

Case in point, I just asked ChatGPT for the best noise cancelling headphones under $200 (their example from the OP) and it cited multiple blatantly LLM generated affiliate blogspam sites. Doesn't really inspire confidence.
