The author lost me when they showed the terminal command to install Nvidia drivers on Debian. Yes, it's one sentence. That's still extremely daunting to the vast majority of computer users. It undermines the author's own thesis.

Linux is a better gaming OS for some (myself included) but there is still a small learning curve. It's nowhere near as bad as it's made out to be, but it's not nothing.

I'd have softened the title and focused on the ways Linux shines as a gaming OS: compatibility with older games (1990-2010 in my experience) that dont work on modern Windows, the ability to get more performace out of older hardware, consistent behavior, and a much more pleasant desktop experience.

Windows is a better choice for many people, but Linux is just as good for many and a better choice for some.
