--==[[ LIBRE OFFICE! ]]==--
because:
1. It's a very good office suite that isn't subject to "fashionable remakes" and other Microsoft shenanigans.
2. over 100 million people use it - mostly on Windows and many on Linux and Mac.
3. No AI! And it certainly doesn't keep track of what you do, and it doesn't call home to tell anyone about you or share a copy of your private documents.
4. No logging into anything or managing licenses.
5. You can download and use it for free: www.libreoffice.org (and it's on Chocolatey and WinGet too I think, if you're in Windows-land) . But of course it helps a lot when people also donate.
7. It has good community support; and there are also options for paid support, training, transition and deployment if you're in a business or organization.
8. There are also written guides in several languages for those who like that format, and there are some video tutorials etc.
and finally:
9. It is managed by a democratically-run public foundation with members from across the world. There are no large companies or governments pulling the strings or calling the shots.
