Because people are making Opera to be some browser that doesn't crash, I mean all browsers crash even on desktops, so if they are looking for Opera to come and save them, it won't be it. But I think Apple should still allow alternatives for those who need it.
Still, anything's better than Safari. On my old Mac, FireFox 2 ran slow, so I installed Opera, because I hated Safari so much that I refused (and still do refuse) to use it. Now FF3 runs much faster and I don't have to use Opera, and while FireFox does crash occasionally, it's far less than Safari. Plus, it quits at predictable times. If I'm trying to load half a dozen YouTube videos while I have several other apps running in the background and I get a SBBOD while using Safari, I can at least understand why it crashed. With Safari, both on my computer and on my iPod, it's never predictable; I might be scrolling through something, and it will randomly quit, even with hardly any stress put on it (like 4 tabs of picture/text). What gives???
Anything is better than Safari, and the fact that Apple doesn't want to allow alternatives just makes me want to switch back to my old Archos even more, which runs-- you guessed it-- Opera Mobile. (And yes, Opera Mobile does quit, but rarely, and at least it does so predictably.)
