Why would anyone use Apache open office over Libreoffice? Also where onlyoffice?

Super.

All are great. Except : Inkscape is decent, except that it's nowhere near illustrator. It's got issues. Issues that maybe casual users can tolerate. A more demanding user won't.

Gimp really isnt a substitute for photoshop. It's slow, unstable and ux is dogshit. Too bad.

If you are interested in audio engineering I would recommend Ardour.

And it's not just for Windows. That's pretty much a list of what came with my operating system.

So.. op complains about Microsoft's interoperability standards, and then proceeds to post a list of apps which mostly use their own too 😂

There's a lot of good software in there.. but misleading caption..

In addition to Joplin, Logseq is really great too, though with more of a text-first, outline based, zettle approach.

I agree these are alternatives, although for the larger solutions, I would argue that none of them are comparable for professional users, besides maybe Blender. I know many animators that use it, but it's more like a tool for a specific purpose, while they also simultaneously use many other proprietary programs.
