Steam is proprietary malware that locks you in with DRM. Stream is mutually exclusive with freedom. By adopting Steam as an ecosystem on Linux, you're turning Linux into what Google did and is still in the process of doing with Android: open-source at the core, but utterly reliant on a proprietary ecosystem to function, reducing the merits of FLOSS to none. Gamers should fuck off and stay on Windows. The "Linux desktop" doesn't need you nor want you.
