Valve could easily enter the OS space. They have hardware and a dedicated user-base. They’ve built some good will with the Linux community. They’re already doing the work to make other stuff work well with Linux. I’m not always a fan of walking too close to the corporate edge with paid software and DRM and proprietary blobs and whatever, but at this point we have to figure out how to get everyone out of Windows, even 100 year old Grandma Geraldine who plays bejeweled on Facebook all day. I probably won’t run SteamOS as a primary OS, but if I could dual boot it instead of Win10 on my gaming PC that would lesson the pain of MS’s betrayal and the loss of some Windows-only games a little bit.
