MIT’s Scratch is a tool developed at the MIT Media Lab to allow young people to learn the basics of computing and programming.
That means it’s also a development environment wherein you can run interpreted code.
Which means that it can’t be on the iPad or the iPod Touch or iPhone. So Apple has yanked it from the App Store.
As the Computing Education blog points out, these restrictions are ending up by saying that you literally cannot create procedural content on these devices.
Discussion on the Scratch forums suggests that it’s because Apple wants to focus on consuming media using these devices, not producing media. Want to be truly computing literate, where you write as well as read? There’s no app for that.
