Yeah I play steam and I believe all the games I play are open source (0ad, openra) even once that are not are old the the source code is available only age of empires red alert etc. SteamOS is the most open source option compared to XBOX and PS4 or EAs Origin etc.
I also watch Netflix,HBO and Hulu, but I do all that with the games is done on an isolated PC game / entertainment using separate router with zero access to my personal data or LAN computer with my personal data or work docs.
I know of SPSS I am from Germany and I used to work / consult for the company during the days when the used open source. For work I use Trueos BSD LaTex and R / python programming language no good data scientist uses automated software like SPSS only analyst do.
I don't care about features of freeoffice I don't want any closed source software near my personal photos, music, vidoes, work PC via lan vpn work docs or personal data.
I prefer to use GNOME and offical edition of manjaro, if it has closed source software I will install Arch with gnome problem solved.
