Tiny websites are great, agreed. The best thing about them? They can be deployed in a decentralized fashion and can protect the visitor's privacy.

This guide however, suggests using Google Analytics which tracks unsuspecting users' browsing history across almost the entire web.

It hosts the website centrally by a Google owned service (which provides even more tracking to Google). It suggests buying a domain name from Google.

Is this some kind of Google advertisement?

No, but no thanks.
