There is a direct analogy to creative writing.<p>The publishing equivalent of Apple would have stifled e.e. cummings for his abuse of punctuation.  You wouldn't have Jabberwocky because it contained imaginary words.  You wouldn't have Joyce because the App^H^H^HBook Store reviewers decided that it made absolutely no sense.<p>The examples above are all of writers tinkering with English, tinkering with writing, hacking the language to accomplish things that otherwise would have been impossible before.  A closed system takes all these away.<p>You shouldn't dismiss the effect of walled gardens on hackers just because you can't or won't empathize with our bit-twiddling.
