Its the other way around; you might be the one seeing a tiny portion (curated blogs, specialty forums like HN etc). The majority of the internet is SEO garbage, LLM garbage and walled gardens
If someone is willingly engaging with the latter things in your post, that's not an argument to burn down the entire thing along with the good things.
I'd wager a hefty sum that most newspapers in say 1890 were also absolute garbage filled with drivel and advertisements, but that doesn't mean they weren't useful or that the average person had to read them page to page.
