Exactly. Game developers should support those decisions where the best, most portable tools get the most attention. Games are immersive and take up the whole screen, so gamers are barely tied to the underlying operating system. It's not like serious AAA games on OS X really have ever used cocoa or carbon. If you made an amazing, mind-blowing game for Linux, then people will figure out how to install and use linux just to be able to play the game. In fact for the younger gamer demographic, getting the system a game runs on for free on commodity hardware is preferable to a wold where you need to pay for a expensive new console every 2-4 years.

Insofar as games are concerned, at the end of the day, the game design matters many times more than the runtime of the game.
