It&#x27;s not the existence of the Mac App Store that hurts, it&#x27;s the existance of this (theoretically) great marketplace that we <i>can&#x27;t use</i> to distribute normal, useful OS X apps. Especially if you <i>had</i> a great little app going in the MAS, and now can&#x27;t update it because it can&#x27;t be sandboxed.<p>And hosting, key generation, payments, etc. are a fairly significant roadblock to shipping an app that the MAS formerly allowed you to completely ignore.
