How are they hurt? The app appears to behave properly (there are no
repercussions, the app doesn't crash, the developer doesn't get punched
in the face). This doesn't make the developer improve his app, nor make
him take greater care for the next app.
Such behaviour will in fact encourage crap since he seems to be getting
away with it.
