Valve might be on to a win^4 situation if they would be able to offer accessible conversion to #SteamOS for Windows 10 devices which are not eligible for the update to the new spying 11 thing. Heck, even for my eligible devices I would consider it.
And yes we as consumers should in the long term move to #Linux or another open source OS, but not everyone is comfortable with a command line and fixing drivers in safe mode.
