The thing this article doesn't cover is that while you can (and imo should) make all these changes, Google will still track much of what you do online.
The internet is rotten with linked media, amp pages, blogs, and ads hosted on Google servers.
If you want off Google, you should use something like Pi-hole to lessen that. Since it's DNS level only, I imagine even that won't make you invisible to Google.
This was a great read, but Google has a million other ways to collect data about you, against your will. That deserves a mention.
