Flash exists for graphic/web designers to make media. Sure, it evolved to move into casual games for the web, but until recently it's been a very second-rate language.
Then there's the fact that Adobe don't treat real programmers with any respect - they don't have an IDE of their own (flex builder is a complete money-grab using the free work of other people) that any serious programmer would use and their whole structure is still aimed around the data rather than the code.
The only reason someone would write an app in Flash is because they can't grok C. It's not as if Objective-C hasn't been around very long.
Add to that the fact that Adobe are trying to pretend to be the 'good' side here... Tell me, why is my photoshop install limited by activations ? Why is it limited to a single platform and I have to pay again if I need to switch between OSX/Windows ?
I won't even go near the quality control of Flash on the Mac. Or the security implications of Flash cookies (that you have to visit an Adobe web page to control

).
Whilst you can argue the merits of 'freedom' or 'control' as long as you like, between the two companies, Apple tends to favour the user and the developer very well - the software tools they provide are excellent and great value and easy to use, generally innovating to make life easier for the user.
Adobe, on the other hand, are so stuck in their ways, often making interfaces more confusing (elements ?), charging old-fashioned high prices for limited license software, and generally doing their best to screw the customer - the only reason they want Flash everywhere is so they can sell more proprietary creation tools at a much higher entry-point than any other language.
Sure - photoshop has some cool features, though many of the tasks people really need it for can be achieved in other software and the majority of things that can't be done are likely because of patents. But that's it.
Adobe - go moan to your designer crowd and get them riled up. Go for it. You know what ? Programmers - those people who write systems and user apps and all the other things that already existed 'before the web' probably don't care... because we don't need flash. Flash is being kicked out by other better, more open technologies and your day is up. You had many years to produce a decent IDE to encourage Flash as a development language, and you didn't bother.
Apple aren't perfect by any stretch of the imagination, but they're nowhere near as useless as Adobe.
