2013: "Linux and open source are the future of gaming" https://www.pcgamer.com/gabe-newell-linux-and-open-source-ar...

SteamOS was released in that year as well: https://github.com/ValveSoftware/SteamOS/commit/0aad7085a1a9...

All of their hardware released since then seems to be aligned with this concept and they have clearly put a huge amount of R&D and funding into this approach.
