Steam is my dirty little secret when it come to my interest in open source. I believe that Valve will continue to hold it’s long tradition of user first business as a private business with lord Gaben at the helm (yes I know he’s mostly in the background at this point). I know that GOG exists however I really like steam forums, achievements, steam deck integration, steam link streaming and most importantly steamVR. Buying through GOG is going to massively impact my steamVR experience if you can even at all. steamVR compared to Oculus makes steamVR look like a very open platform. I hate Facebook with a passion for a variety of reasons so steamVR it is.
FOSS is a great tool/concept but at this time it doesn’t apply to gaming and I don’t really care to massively inconvenience my gaming experience for a small amount more of open source code. I say this as someone who daily drives a PinePhone, runs a Linux server with ZFS and is looking at a Framework laptop for my next laptop to run Linux on. Windows is still where gaming is at, especially for VR, and I don’t care to try and fight to run close source games on an open source operating system. Seems like a waste of effort to me.
