I agree. It's not that the web was high-trust. It was more that if you landed on a niche web page, you knew whoever put it together probably had at least a little expertise (and care) since it wouldn't be worth writing about something that very few people would find and read anyway. Now that it's super cheap to produce niche content, even if very few people find a page, it's "worth it" to produce said garbage as it gives you some easy SEO for very little time investment.

The motivation for content online has changed over the last 20 years from people wanting to share things they're interested in to one where the primary goal is to collect eyeballs to make a profit in some way.
