I know that there are plenty of bitcoiners that are still on Windows/Mac and not using a Free and Open Source operating system like Linux.
And I get it. Linux can be confusing and tough to get into. If you're deep in a certain tech ecosystem, that also complicates things.
But not running Linux is like having a custodial PC. You don't truly own your computer. You're not free to audit, modify or run the software as you see fit on your own computer.
At the same time I recognize that perfect is the enemy of good. Replacing your entire operating system probably seems a bit drastic. So I would say to start replacing some of the non-linux compatible and proprietary software with FOSS alternatives.
Outlook -> Thunderbird
MS Office -> LibreOffice
Video Games -> Read a book
Also, with WINE and some other workarounds there's usually a way to get a lot of your old apps working on Linux with a few (although admittedly big) exceptions.
Remember, the "free" in software means: free as in freedom, not free beer.
Libre not gratis.
