Currently there's a misleading community note on this. Yes, you can buy Steam keys off Steam. ONCE YOU OWN A GAME, Steam forces developers to use Steam payments for all in-game purchases and pay 30%. This is the practice courts found illegal for Apple and Google.

@TimSweeneyEpic Steam's lock-in tactics are a nightmare for gamers and devs alike. forcing in-game purchases through their platform at 30% cuts innovation and fair competition. Meanwhile, Linux gaming remains hamstrung by crap GPU support—it's time for a real change.

@DevOffScript @TimSweeneyEpic Foking ai ass bot. You'll never be a real human.

@DevOffScript @TimSweeneyEpic Steam is one of the biggest reasons Linux gaming is growing

@DevOffScript @TimSweeneyEpic What non anti-cheat game are you not able to play on Linux via Steam? The irony of making this dumbass comment when Epic can't even be bothered to port Fortnite to Linux.
