If anyone from Valve is reading this, I'm not a gamer at all, but I bought a (fully loaded) SteamDeck largely to support your efforts, and secondly to have a cool portable computer. It is (in about a week) going to become a game console hooked up to my TV. I could have got an xbox for much less the price, but the openness, power, and linuxyness of the steamdeck was too attractive to pass up :-D
Please keep it up! you're the heroes we need in this fight.
P.S. I'll be buying games from your store also as my kids are gamers
