From the OPs screenshots, his app was perfectly usable to many, but the changes are clearly an improvement. Yes it's subjective, but the bar is not set impossibly high, it's set just high enough to maintain a minimum of quality. Honestly speaking, the changes the OP made aren't exactly the pinnacle of great design either, but they are a huge improvement. Apple is focusing on the user's needs by ensuring some degree of quality in the apps they use. There's enough diversity in apps and app design on the AppStore to show that Apple isn't enforcing a single ideology/design style on developers, just trying to maintain a modicum of quality.
