I guess all those games work out of the box in linux through steam. I personally play just Stellaris from that list, but I do not see why the others wouldn’t.

Oh, I agree with that (I use a selfhost solution -gitea- myself). I was just pointing to what I think is the current situation and why is like that :)

Well, keeping an infrastructure like github is very expensive. Other solutions like gitlab are no real solution as gitlab itself is also not completely FOSS. Codeberg is a relatively new kid in the block, and sustainability in the long term is still not proven. Gitea/Forjego requires you to selfhost your repositories and that’s something not everybody can afford/take the time to do.
So, we have a situation of a standard de facto, when one company took the space and constitued a monopoly, forcing the users to use it or be invisible otherwise.
So, there you have the reason: visibility in a market dominated by just one actor.
How to fight this situation? There is no much way as individuals, a partial solution is to use a FOSS solution and then mirror on github for visibility. Of course this is limited as individual solutions wont change collective problems, but FOSS groups doing the same are no longer individuals but communities so with time we may have a way to get out…

EDIT: s/go/get

lol, I was doing exactly the same, mostly because the gnome app for it (webapp-manager) does not do one thing I badly want : open all non-app links in the default browser and not on instances of itself. Also, I love the webkitgtk project and this allows me to give it an usage.
I will give a look at your project, I think is better contribute to it than have two (or more) projects doing the same 😜

Manjaro. I am a guy of habits, so I never really distro-hopped, I once tried to install Arch and failed to configure everything so I tried endeavour and failed too (which would mean I am not a tech guy either ;). Ultimately, I’d say that the distribution does not matters much once you are used to it, you can always get what you want from any of them. The only thing I really like in comparison with others is pacman :)
