Unfortunately, that exception kind of proves the rule. Apple left in a loophole - they kind of had to allow apps to link to arbitrary external content without registered authors - and, lo, through the loophole comes malware.

This, alas, is why I'll probably have to keep buying computers instead of just the iPad if I want to run emacs or other user-scriptable apps. To the extent that it is possible, Apple wants every line of code on the phone to be traceable to an author and revokable in case of trouble.

The exception is the web, of course. Apple's browser supports everything; if you want arbitrary power, write one of those web apps we've heard so much about for the last decade! We who aspire to use emacs on iPad now need an HTML5/JS version. It's like being boiled in our own Kool-Aid: people have been claiming for years that web apps can eventually replace all other apps, and now the rubber meets the road.

Isn't this the same old DRM/Terrorism loop where every breach of the pointless and/or ineffective restrictions is used as justification for the next round of pointless and/or ineffectual restrictions. And along the way you the honest consumer/citizen lose the ability to modify your device, to reverse engineer, to crack protection for any reason, and various other 21st century civil rights as collateral damage.
