GamingOnLinux follows up on a reddit post and confirms that the number of SteamOS titles on Steam actually went down recently. The speculation is that they are removing this from titles that don't operate perfectly under SteamOS, even if they work properly under more traditional Linux distributions, to avoid confusing or disappointing customers after SteamOS leaves beta. They also reassure Linux gamers that none of these games have been removed from anyone's libraries, and that they can still be installed and played as before. Thanks Ant.
