As a professional who gets work done with Linux, I disagree. Lots of desktop environments (KDE, XFCE, Cinnamon) offer a UI is just as polished as mac or windows. Lack of suitable software can be a dealbreaker for some professions. There aren't many professional video editing suites, for example. But in companies I've worked at, most workers only need a browser and an office suite to do their jobs. Linux would work for them. I think the real obstacle is training. You have a workforce that's already used to the way windows works. It's easier to hire IT people with windows experience than it is with Linux. Users know how to do their tasks in Microsoft office, and even though Libre office is similar, they might have to learn a few new things.
