However the recent success of gaming-related distros such as SteamOS and Bazzite seem to be succeeding where Usability-focused distros such as Mint, Pop!, and Zorin couldn't get deep traction
Ubuntu is "like Windows but not" which is mostly relevant to people boycotting Windows. Steam Deck is "a gamebox" which people who already like games might want to buy. Bazzite is "a thing that turns your computer into a gamebox." Of course, people don't actually want gameboxes either - they want to play games - but it's a few steps closer.
Also lets not forget those distros play Windows games, because hardly any studio bothers with native Linux games.
Game studios will keep buying Windows, using Visual Studio, and let Valve do the needful.
Additionally people keep acting as if Valve and Gabe will be around forever, they won't, none of us will.
And there's Android.
I would look into those statistics regarding desktop world wide adoption, distribution per OS.
It gives a Linux experience within the security sandbox from Android, which is why there are limitations when using it on regular devices, via PlayStore.
Also it requires working around the NDK limitations on available POSIX APIs.
Linux is not userspace. Linux is a kernel, and android is a parallel fork of the kernel. So android is a version of linux but is not GNU/Linux.
Android/Linux, if you will. We dont have to be shy this.
GNU/Linux, the Linux desktop, has zero relevance on Android.
No one, not a single person, buying Android tablets and phones at places like MediaMarkt, cares about GNU/Linux Desktop.
They care about what apps via PlayStore, Samsung, Huawei and Xiomi stores, they can use, just like all normies.
