SteamOS being open source would solve a lot of problems including the keyboard. Users should be allowed to customize their U.I has any Linux operating system. There’s no reason why they shouldn’t.
Again you should not trust Valve for anything. There’s enough lawsuits to prove they lied to everyone. Gabe is part of the list of liars, claiming better Steam Deck and after a year it’s a joke performance.
Valve has not been pulling their weight. Hiring people and letting the community work on Proton isn’t a good thing. GitHub history shows zero work on Valve employees or developers of Proton. Only the community has updated the system not Valve, don’t give credit to lazy cheapskates.
