Oh come now, there are millions and millions of professionals using macOS to do work every single day.
This is basically a slippery slope fallacy. Today they're making it marginally hard, what might they do tomorrow?!?
There are many reasons to prefer macOS to Linux or Windows. The Apple ecosystem works extraordinarily well together. There is nothing that you can buy, not with all the money in the world, that matches the seamlessness of owning an Apple Watch, iPhone, iPad, AirPods, and a macOS device. You can't do it with Linux, Windows, Android, or anything else. It doesn't exist.
I prefer macOS for development work, and for basically any kind of work. I loathe the Windows UI/UX and Linux is far too often a second (or third) class citizen. There is nothing that I have needed to do that I have been unable to do because of macOS. Not once.
Not to mention... if you want to write software for macOS, iPadOS, WatchOS, or iOS you must own at least one Mac.
