I don’t fully understand apples argument here of “we can’t moderate everything” They’ve allowed the Steam Link app on the App Store for a while now. It’s Remote Desktop to my PC and I can play loads of games through it. That’s barely any different. Steam made the store functionality less built in, so it’s harder to buy things, but it’s still game streaming. There are loads of Remote Desktop apps on iOS already, is the difference that it’s “end users machine” vs “cloud”? Or that it’s a subscription? I don’t understand.
