What does HackerNews think of degoogle?
A huge list of alternatives to Google products. Privacy tips, tricks, and links.
Not specifically google but tries go from "do know evil" back to "do no evil" https://www.privacytools.io/
As noted in https://github.com/tycrek/degoogle/blob/master/MIRRORS.md for GitHub Pages: "I am using my personal domain as some firewalls block GitHub"
To be quite honest I would prefer to not use GitHub either, but in the interest of easy collaboration GitHub is the optimal platform to manage the project from.
Don't get me wrong: I totally agree with the irony of using a Google TLD. But as @franksvalli said, I do not use AMP, Angular, or Google Cloud. Any tracking done on that page is from GitHub Pages that I do not have control over, unless I make my own auto mirror for that domain.
