Other portable console makers: proprietary shit, locked down OSes, DRM embedded in the device at boot, custom/strange architectural choices, walled gardens
Valve: eh, put a fuckin' normal ass gaming PC in a tiny box with joysticks and call it a day.
Theyâre focused entirely on the shitty practices those other manufacturers engaged in. In that regard, Valve didnât do much (and thatâs a good thing).
