LibreOffice is free and open source and also brings in free document types which are not restricted by Microsoft.

Libreoffice lacks in some point of support Microsoft only document styles but you can create fully functional documents shareable with any Microsoft office Suit.

It's free and open source software. Compatible with most Microsoft Office documents. Doesn't track you at all.

CryptPad vs Microsoft 365 Copilot Comments

I like Cryptpad as an alternative to M365, where it allows you to self-host your own office suite, which looks like an instance of OnlyOffice hosted in the "cloud" while respecting E2EE and is open source. If you'd rather use the cloud than self-host you can use a public instance or a paid plan for hosting and storage.

I was using only Libre Office for years on Linux. Now I use FreeOffice and Latex via VS Code the most. FreeOffice is fast and streamlined, the UI is well built and looks good, very compatible with MS proprietary formats. It's also available for several platforms. There's a commercial alternative with more features too if you need support. Just try it.

the free version is too limited with less features annoying watermarks on PDFs. if you want the complete version with all of its features, it's expensive.

Calligra Suite's interface kinda resembles iWork (is it still called that?), which would come as a shock to those coming from Office. Unfortunately, I didn't have a stable experience using it on my device running Zorin OS. It also lacks collaborative features.
