Microsoft Office is not "niche professional software"

What is Microsoft Office? Do you mean Microsoft 365 Copilot?

You forgot the "App" :) I'm still astonished at how dumb that rebrand is...

The "app" isn't even capitalized, which is my favorite part!

*Microslop 365 Copilot

Well played sir. Well played

I suspect the person you are responding to wasn't including everything that doesn't work on Linux, in particular Microsoft Office, in this phrase, but domain specific / specialized business software.

I have two Windows systems; I use LibreOffice on them. It's just so much better.
