Gets a little chuckle from me that Nvidia and Nintendo signed the contracts but Valve is like "nah" whilst still supporting the deal.
I know Gabe said he doesn't believe in contracts like that and trusts Microsoft but I've a feeling that he simply doesn't give a shit as well, Lol.
Like they didn't care when EGS went on their mad moneyhat crusade either.
Gabe is either a very chill man or knows Steam has complete dominance over the PC market and nothing will hurt that.
