I wanted to jot down some of our thoughts on Adobe's Flash products so that customers and critics may better understand why we do not allow Flash on iPhones, iPods and iPads. Adobe has characterized our decision as being primarily business driven – they say we want to protect our App Store – but in reality it is based on technology issues. Adobe claims that we are a closed system, and that Flash is open, but in fact the opposite is true. Let me explain.

You can read them here. Although we await Adobe's inevitable reply and will happily link to it here, this is a pretty strong articulation of the anti-Flash position by Jobs or whoever worked on this letter. Interesting that he spends so much time talking about openness.
