So what are the goals here?
The primary goal of this guide is to minimize your digital trail, and reduce the amount of data collected about you by big tech. At the more simple levels the steps I outline will not even be inconvenient, or impact your day-to-day use of technology. Many of them even make your devices and the websites you visit feel faster because they're not working so hard to track you.
While all the advice here is effective across the board, the primary goal is reducing tracking by the biggest central offenders: Google, Facebook, Twitter, and Amazon.
You'll also likely find advice suggesting Microsoft alternatives to the offerings of the big offenders. This is because, barring switching to Linux, you are likely already using Windows, and I figure if you can reduce your footprint from "tracked by Google, Facebook, and Microsoft" to simply "tracked by Microsoft," that's actually a big win.
Ideally everyone would take this all the way, and go all in on open source, and only use open source everything, but in reality that's simply not possible for everyone. Maybe you need to use Adobe for work. Maybe you need to use Office for work. Maybe you just don't feel up to reformatting your computer and putting Linux on it (it's a big step, I know). My goal here is to offer a thorough digital privacy guide for the everyman, without the open source zealotry that honestly holds us back in a lot of spaces.
There's a reason I called this the pragmatic guide to digital privacy. It's not just for zealots. It's not just for nerds. It's practical steps that can be taken by anyone.
