I made this post because I am really curious if Linux is used in offices and educational centres like schools.
While we all know Windows is the mac-daddy in the business space, are there any businesses you know or workplaces that actually Linux as a business replacement for Windows?
I.e. Mint or Ubuntu, I am not strictly talking about the server side of things.


Lots of justification in this. Just be the change you want to see.
I only work with libre formats at work. If someone wants to collaborate, they can easily install libre office or gimp or freecad or gnu cash or whatever. Most libre software is free and cross-platform.
