It's not the existence of the Mac App Store that hurts, it's the existance of this (theoretically) great marketplace that we can't use to distribute normal, useful OS X apps. Especially if you had a great little app going in the MAS, and now can't update it because it can't be sandboxed.

And hosting, key generation, payments, etc. are a fairly significant roadblock to shipping an app that the MAS formerly allowed you to completely ignore.
