Free Software Foundation and GNU operating system founder Richard Stallman believes it’s “unethical” for Steam to sell DRM-protected games on an open-source platform like Linux.
“Any GNU/Linux distro [distribution] that comes with software to offer these games will teach users that the point is not freedom,” said Stallman. “Non-free software in GNU/Linux distros already works against the goal of freedom. Adding these games to a distro would augment that effect.
“If you want freedom, one requisite for it is not having non-free programs on your computer,” he wrote, stating Linux users should source titles from the Free Game Dev Forums instead.
“However, if you’re going to use these games, you’re better off using them on GNU/Linux rather than on Microsoft Windows.”
Valve hasn’t provide a window for when Linux will be supported, but it announced a Linux version of Left 4 Dead 2 will be the first compatible title released.
