My assumption is that both the businesses trying to provide services and products as well as the average customers do generally not care enough about privacy. On the contrary, while the average end user does not even know how deep modern browser fingerprinting and tracking goes, the average e commerce platform is intetested in gaining this valuable data for profit.

In the end it turned out to be mostly an ad for Cloudflares DNS service. Just like other big internet companies they are big enough that they can track users across the web, even regardless whether someone uses their DNS service. Companies like that degrade user privacy.

What we actually need to change if we want privacy is the browser permission system and javascript. The user needs to be in complete control of local resources and code while browsing the web. An in-browser firewall à la LittleSnitch would be a good start.

In my opinion, "Phase 3" of the internet is end-to-end encrypted, no middlemen.
