Honestly, if steam has to cut the 30% fee, its just more money for the Devs. Cross Plattform dlcs? Hell yeah.
I honestly dont See the problem with the lawsuit. Sure, its a loaoboll'ks mayt`, but why the fuck not? After all, why shouldn't steam get even better than it already is?
They might make this an excuse to do those things, sure, but Valve has more money than they know what to do with.
