GNU/Linux like proper laptops and desktops, not gaming handhelds.
100% of the gamers that don't overlap with FOSS folks, don't care SteamOS is somehow based on the Linux kernel, the Steam Runtime and a Win32/DirectX translation layer, otherwise there would not be games to play.
The steam deck is essentially a laptop (and I think made it through FCC on that basis). Plug in a USB hub, HDMI, keyboard, mouse, and I'm all set. I actually bought an extra one because now that the mobile device ecosystem is locked down so completely, it's my main escape hatch for a portable PC.
What, prey tell, is a “proper” laptop and desktop?
Plug a usb dock into the steam deck and you have a “proper” computer.
Calling a Linux distro Gnu/Linux today is wrong because the actual Gnu code running is such a small part of everything.
SteamOS uses Linux as much as Linux distros like Fedora and Arch and other Linux based systems like Android.
A lot of gamers are also FOSS folks although not as hardcore as RMS.
Not at all, it makes a point, ChromeOS, WebOS, Android, are also based on the Linux kernel and hardly considered Linux distributions for everyday use, in a way similar to GNU/Linux expectations.
How little do game studios care to port their titles from Android/NDK into SteamOS, even though both are "Linux".
You have a misunderstanding. SteamOS is essentially Arch Linux.
Edit: Misunderstanding is mine. I think you guys are discussing something else. I was trying to assert that SteamOS is GNU/Linux, unlike the others.
Android and iOS games are usually not interesting for SteamOS gamers.
What really makes ChromeOS different from Ubuntu except it is not developed in the open?
Userspace is a browser.
