Having used Linux in various roles for nearly 20 years, I have to agree. Supporting Windows is hard enough when you have to tell the customer over the phone to click on the circle or flag thingy in the bottom left corner, because they haven't heard of the "start" menu, and have to hunt through Windows 10's old and new control panels. This is nothing compared to the differences between two contemporary distributions of Linux, with a choice of package managers, system init, and window managers. The dimensions of brokenness possible on Linux are generally unseen on Windows.
