This will be true once the stability of graphics drivers on Linux improves. On every major kernel update, I am always bracing for everything going blank because of driver issues.
Additionally, the Nvidia problems under Linux are very well known, so getting a Nvidia GPU for Linux is a self-inflicted problem.
It also possible that people who find out the Nvidia cards are unreliable on Linux are making decisions over other systems where this shouldn't be such a big deal.
When windows users try Linux for the first time, they'll (rightfully) point out problems, while their Linux friend will just say "oh that's normal, you just have to do Y" and the exact same thing would be true in the reverse situation.
Some people are just more tolerant to being in an unpredictable environment than others. I find myself highly tolerant to noise, unpredictability and things breaking. Of course I have my limits, but when comparing myself to my best friend, he will literally have none of it (he's a macos user)
I wonder how many HiDPI users also complain about global warming in other forums.
