Linux users (me included) are only a few percents of all PC users. I don’t think they did it for us as a market, more to have an alternative to windows if they start closing down more (started with Windows 8 I believe). First try they fumbled a bit with the Steam Machines (Stream OS and proton weren’t there yet and the prices were not really competitive) and now nailed it with the Steam Deck. I do love that they seem to care about openness to some degree!
