Different people have different workflows. Documents is something I create using LaTeX and Emacs Org Mode. I have almost no use for things like word processors. I spend most of my day in a text editor and using windows would slow Emacs down. I don't expect everyone to work like I do, so you should not assume that everyone uses word processors for their work. Libreoffice Writer is totally sufficient for the rare occurences in which I want to use one. I am the only Linux user at my workplace, all the others use Windows or MacOS and so far I have never used anything except Linux in my professional life. If you need specific features from word, excel or need to install Photoshop or games, I understand your need for a different operating system. My needs are different, I need a system which I can adapt to my wishes.
