Show HN isn’t advertising in the sense they are addressing: paying a website for space to promote something. There’s no payment taking place with Show HN. If no payment can be made, websites have to find another revenue model besides advertising, and don’t have an incentive to keep users addicted and endlessly consuming.

Nah, advertisement in general. Just make the internet a paid sub. We don't need influencers or snake oil ads. And without ads and influencers, there is no reason for meta to try to keep people infinitely stuck to their phones. They can get their cut just from a paid sub.
