If this is what AI ends up as it'll be fine. Those ads are easy to detect and block. The danger is if the ads are far less intrusive, so an advertiser bidding on which hosting company to use would be the only result mentioned in the text, or the examples are all pointing to one player, or worst of all, examples for more than one but only the bidder's examples actually work properly. An ad-nerfed AI could be made to hallucinate non-working example code for anyone that isn't paying. Done subtly that could shift marketshare from an incumbent to a new service very quickly.

We've seen this happen on Google's results pages. Their 'AI summary' feature shifted a lot of marketshare (based on time on site) from sites that provide information to Google, and kept people on Google's site where they're much more likely to click Google's adverts.
