With the widespread support for Steam/Valve on this forum because of their contributions to making Linux gaming easier, I'm now confused as to why people here are using Linux in the first place.
I personally do so out of support for FOSS software, the customizability, and actual ownership of software, which I thought were most people's primary reasons for using any Linux distro. Steam seems antithetical to all of these. The software in the first place became popular as a form of DRM, and it gets publishers to use it for the allowance of DRM on the platform. The Steam client has the absolute minimum customizability. Your account can be banned at any point and you can lose access to many of the games you have downloaded.
Whenever I game on Linux I just use folders to sort my game library and purchase any games I want to play on itch.io or GoG. On my Linux PC I stay away from clients like Steam because I want a PC that works offline, and will work if all of my accounts were banned. It's more of a backup PC.
Since Steam has every characteristic of Windows, 0 customizability, DRM, plenty of games that are spyware, I see no reason to really not use Windows instead for the much easier time I can have playing games.
Yes, I prefer many of the features of Linux distros, but using a client like Steam defeats the purpose of them. Ridiculous storage requirements due to unoptimized dependencies, having to have a background client running for some games and wasting resources on doing so.
So, why use Linux and support Steam, or use Linux and use Steam?
Made the switch way before any kind of support from steam, had several games from aspyr and feral, bought a codeweavers license and all that. For me at keast it's about the lack of interruptions and actually enjoying the workflow on gnome. I also love the idea of fetting in touch directly with the people making the programs I enjoy and not a random support rep on the other side of the world.
On the other hand, you should probably take a deeper look at steam. There are a ton of extra modifications you can do to the client, all of them unofficial and some straight up illegal, from changing the theme to injecting enhancements on the store (e.g. displaying protondb score on store pages) to aome shady shit like unlocking DLC. Steam is DRM but it's not denuvo or something like that. It's easily circumventable to the point I feel safe buying games on it, knowing if they ever go for a rug pull, I could keep most if not all my stuff regardless of the platform itself.
Steam will let you play pirated games through their Proton and compatibility framework. What kind of DRM is it truly if it helps you pirate?
