Only if you understand desktop market share of an operating system as a battle.
Myself and a lot of other people are using GNU/Linux and other libre operating systems with great pleasure and, finally, growing hardware support. I could not care less if 90% of desktops are Windows systems or if an additional 9% are OS X machines or whatever.
tl;dr: Just use what works for you. If it supports your ethical values, itäs even better!
Sure, if all users believe in "use what works for you", they shouldn't get pissed off when others make jokes on that. *nix users are not going to like it, but in real world comparisons are bound to happen for things of same categories and you can't prevent that. Better to move on, and that was the reason I wrote my comment.
