Yes! Been waiting for this:
‘Valve, creator of the Steam gaming platform and a video game studio and publisher in its own right, is the latest company to join the Linux Foundation – a nonprofit organization tasked with nurturing and advocating the open-source operating system.
The move isn’t much of a surprise, given that Valve adopted Linux for its recently unveiled Steam OS, an operating system that will be used for a new range of third-party video game consoles called ‘Steam Machines‘ expected from mid-2014. Valve co-founder and CEO Gabe Newell described the operating system and open source movement as “the future of gaming” at LinuxCon a couple of months ago, following the release of an official Linux client for the Steam platform in February.’
