Yes, the Steam Deck is great, and Steam is definitely one of the best games platforms there is. And Valve has done great work supporting Linux and open source development, and forcing more transparency for sellers on Steam.
But I feel like people sometimes just love valve for everything they do. GabeN is still a billionaire, buying super-yachts and stuff. Valve makes a ton of their money from gambling on loot crates in CS2 and TF2, and have not done enough (imo) to stop even more predatory third party item gambling sites. And whenever I bring stuff like that up people keep defending Valve.
We should be able to praise their great games and hardware, at the same time as criticising other parts of the company.
Is he really doing a lot of shady things? Maybe he just become a billionaire and adapted. For better or worse is the question, then compare him to the other billionaires. Having that amount of wealth changes people just like it would you or me and every other person here.
