I totally agree about the subscription being worth it for most heavy users, but there are a lot of people in the developing world for whom $20/month is hard to stomach. I think it's good that those people have an option to get more access to AI with lower out of pocket price.

I agree that it won't be an unbiased source of information, but should be roughly same level of trustworthiness as clicking on the link and reading the information on the advertiser's website.

Yeah, basically this. Some people really do click on ads that are relevant to their interests and might want to learn more or be able to ask questions about the product. I'm not confident about how well it will work in practice, but I could imagine cases where this would be more helpful than clicking on the ad link and needing to explore the resulting website to find the information I want.
