What about Valve itself? They have ~350 employees. They make Steam, SteamOS, Steam Deck, Steam Machine, Steam Frame, the Source engine, and run four actively successful live service games: CS2, Dota2, TF2, Deadlock.
I know they're sponsoring a bunch of ARM and Linux projects as well.
Having skilled and happy employees that aren't constantly changing and do not spend all of their time on ways to fuck over customers and chase trends is simply impossible. Releasing a piece of hardware and leaving it open for customers to do with what they want? Linux? Not hiring people the second line goes up and then immediately firing them when line stagnates? Preposterous.
