So blame greed for Steam retaining its dominance. Companies wanted the cake to themselves and failed to see the bigger picture that federation would have been a better idea. Develop a common platform that handles sign on, updates, achievements, anticheat, matchmaking, discussions, forums, reviews etc., but does NOT include a store. Companies would be free to sell their games however they liked from wherever they liked. The system could still have had a landing page or a promotional aspect but purchases happened elsewhere, possibly using SSO to make it simple and easy.
It would have been a more successful and fair system than what actually happened.
I certainly don't see the point of jumping from Windows 10 to Linux without considering that a lot of games aren't going to run any more. If you play predominantly through Steam then the pain isn't so bad because of Proton (WINE) emulation and some native builds. But anything outside of Steam, probably won't run at all, or only by screwing around with WINE or some variant, trying to circumvent DRM and the like.
Anyhow, the main driver for Linux gaming is obviously Steam Deck and Valve's efforts to make it as painless as possible for developers & gamers to run on it. As a side effect Steam also runs on desktop Linux and existing Linux users enjoy some gaming support.
I doubt many people using Windows 10 for gaming would see the attraction of switching to Linux when it would be easier to stay put, or switch to Windows 11 and continue to play every single title they own.
Government really need to get on top of this and require AI generated content to be watermarked and very clearly labelled on social media platforms.
