I don't get this. We never discuss iOS App Store or Android's Play Store when an OS update comes out. It's just a program to a new Operating System.
Er, maybe not when an update comes out, but about iOS in general? I've sure heard and read plenty of discussions about the app store. The iTunes / App stores is specifically the reason I do not want an iPhone (again).
In this case, I get that its linux, but its Valve's branded linux. Complaints about Steam, the impetus behind the distro, are completely relevant.
