I want to put your post in the context of yesterday's HN front-page post lambasting the EU for trying to build a better search engine. The bulk of the comments suggested that a government effort could never be as good as a commercial effort. https://news.ycombinator.com/item?id=32915263#32916945
Your post is a strong counter-argument. All of the points you mention on the massive decline in quality of web content are due to the web being driven by commercial efforts.
Likewise, comments on this current HN front-page post "Despite faster broadband every year, web pages don't load any faster" https://news.ycombinator.com/item?id=32945858 also seem to explain the poor state of the web as being due to commercialization of everything (even the comments about the need for cookie banners-- the logic behind the cookie consent is to regulate the commercial collection of user data).
Google started as a DARPA project, and was a great engine while it stayed true to that ethos. It was the need to commercialize it, thus setting perverse business incentives, which has destroyed it.
Your post praises libraries. Which are seldom commercial ventures.
The economics are simple. I don't know why this even continues to be a debate on HN.
- A socially created entity (corporation, government, "charitable" organization, ...) needs money to function.
- Money comes from capturing a portion of the value created by the organization.
- The most efficient organizational structure depends on the relationship between value creation and value capture.
Thus: if the product/service generates immediate and focused value, the value capture can be directly linked to the product and a business is optimal. Think: a hamburger.
If the product/service generates long-term and diffuse value, the value capture also needs to be diffused, i.e. taxes. Thus a government. Think: the road network which allows the raw materials and the customers to get to the hamburger store.
I leave the case for charitable orgs as an exercise for the reader :)
