That's what bothers me about the article. I can't think of a single piece of professional production software that is Mac only, apart from Apple's own apps like Final Cut Pro and Logic. Those are great apps but they have equivalents on Windows, and some of the Linux pro audio and video apps are getting really good. As for web development, there is nothing you can do on a Mac that can't be done on Linux or BSD apart from testing in Safari, and Safari has a smaller user base than IE/Edge. Hell, even Windows is improving in this space. I guess one could argue that macOS is a more aesthetically pleasing environment to work in, to which I counter that I'd rather work in BeOS/Haiku as I find it more aesthetically appealing than any other OS. In other words, that's purely subjective.
