And it's a safe bet that Apple will be checking submitted apps to see if they were created using Adobe's technology. Or any of the other cross-platform non-C/C++/Objective-C tools, for that matter.
It's easy to imagine Flash developers reacting badly to this. Just as they were about to get a relatively easy way of porting their work to the iPhone family, Apple's snatched it away from them.
Some commentators are putting forward the argument that this is essentially a 'quality control' measure on Apple's part. I'm not convinced by that.
While there are a lot of excellent iPhone apps in the store, none of my iPhone owning friends are claiming every app is of good quality, and Apple doesn't seem to set the quality bar very high.
And that's arguably how it should be. Apple's welcome to check that an app basically does what it claims, doesn't do anything underhand or accidentally destructive, and doesn't use unpublished APIs, but that's about as far as it goes.
So who stands to benefit from the change? See page 3.
