You are talking about consumer marketing. I am talking about B2B marketing for prescription medications, enterprise SaaS, etc. These are separate markets and the analogies don't quite hold here - the scam problem etc is practically nonexistent for high-LTV goods with high bid costs, and newcomers are typically well funded enough to periodically outbid incumbents (or implement better targeting). The big-ticket B2B products that one hears of from word-of-mouth are usually the worse ones, since there is rarely any "going viral" to speak of.

> That the engine's website puts a different thing that whatever the search algorithm thought was the best thing at the top because an advertiser paid for it to be so, is strictly worse.

This is not clearly worse than the result being selected by the whims of some arbitrary Google engineer, or being easily gamed by SEO blogspam bots. At least the advertiser stands to lose something if they bid incorrectly.

>How long had ChatGPT been out before OpenAI's first ad for it?

Just because some products were able to grow organically doesn't imply that paid marketing never benefits startups. This is a false equivalence.

I also find it funny that the vast majority of your example products (everything except Huel or Aeropress?) make a lot of money from advertising. Maybe consider why they still exist.
