There's definitely a desire for an appliance/console like experience where all the complexity is hidden behind install/play buttons, and steam has got most of the way there. As protondb shows that can't go all the way and tweaking is needed owing to the shifting PC compatibility in general and running software from one OS on a different one, it's the nature of the beast. Personally pushing towards monoculture on an open platform needs to be tempered, and there's a lot of debate previously for other places where that's relevant.
I think there are several segments that want one true way (their way).
The arguments are tired, the word serves us well. They insist, yes, and forever remain hopeful that This Might Be the Year. Meanwhile, the reality exists for plenty already.
And what of it? Every time a for profit company uses open source they'll either create a closed fork, and if they can't they'll create closed source modules for it.
I'm not saying it's bad to wish for companies to support FOSS, I'm just saying it's an unrealistic expectation to have.
