Additional later note: the actual court case here does, in fact, argue that requiring that all app prices end in 0.99 means Apple is dictating pricing terms, which on some level is of course absolutely true, i.e., it's Apple's fault I can't price my app at $1.49, or $3.33, or whatever. But (1) that still doesn't prove that the 30% cut is harming consumers, which is what American antitrust law is relentlessly focused on, and (2) if that's the crux of the argument, it can be addressed simply by removing that restriction. It can probably be met even if Apple says "you can price your apps anything you want to, but if your app is not free, we're going to take a minimum 29¢ cut."
