> HN itself is a massive ad

I don't think it is the same. There is no manipulation involved here and many people seem to be looking for jobs actively.

> no one actually wants to pay

Two things

1. Most content is actually pretty worthless. It's subsidized by the ad-surveillance industrial complex. Even in the pre-LLM times there is so much blogspam, content farm articles, and slop videos because of this.

2. Payment monopolies have made microtransactions uneconomical through fees, which contributes to the friction of paying. I imagine in an alternate world with a crypto or fiat based digital currency with low enough fees, there would be much more direct payments. Seriously, if you just pay one cent per Youtube video, it'd dwarf the ad income for most channels. Your attention is hilariously worthless.
