Linux: It’s not just Microsoft Office you can forget about, but all of Microsoft’s offerings, including Microsoft Windows itself. You can probably get rid of Mac OS too. Why? Because Linux is free and open source software that is not just “libre” but also often costs you as little as nothing. There are literally hundreds of different Linux distributions (or “distros”) to choose from, and you can find the one for you via LibreHunt: https://librehunt.org/
Are there any good alternatives to Distro Chooser these days? (https://distrochooser.de/en/)
Many years ago, I had also recommended LibreHunt.org, but it's no longer available.
