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…

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.

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

And it’s not just for Windows. That’s pretty much a list of the default choices for my operating system.

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.
