People in these parts honestly believe Android is a hospitable business environment, but if your business involves selling things, you have to content yourself with a tiny fraction of iOS's revenue potential. That's why these guys aren't pivoting. Their business wouldn't have existed in 2011 without iOS.
I sell an SEO app ( http://semtab.com ) on both iOS and Android, and the Android version is outselling the iOS one by a wide margin. It caught me a bit off guard because everyone I know keeps repeating that iOS users buy more than Android ones, but that just hasn't been my experience so far. I even put the iOS version on sale at $0.99 in hopes to increase purchases, but it is _still_ not resulting in as many purchases as the Android version at the original $1.99 price.
I think the root of the difference is indeed competition on iOS, and lack thereof on Android. The lack of any decent SEO app on the Android Market is the primary reason I made SEMTab in the first place. I think that is the biggest reason it is selling better there - it's easy to stand out when all the other apps on Android are total crap.
Or perhaps you discovered that there are more search engine marketers on Android than on iOS. Or that your app has more visibility on the Android market. Or multiple factors unrelated to the average user's general app-purchasing habits.
Heh, I guess with Nokia's pivot, I should have said WinMo7, but I had actually forgotten about its existence. The point was that there are other phones out there, with app stores that people (apparently) use. I can't imagine any environment (even Meego's) being less business friendly than Apple's, at this point.
I think my actual point was actually that Apple has been great for developers not hostile as you claimed. I think that's true by inspection. I think this developer had a terrible business model that was exposed by entirely predictable changes to market conditions and went out of business and is lashing out.
Eh, the fact that Apple has been "great for developers" is largely an accidental consequence of the fact that their platform has a lot of users who are willing to spend money. Apple attracted the users because Apple wanted the users, not because they wanted to help developers out. Without the userbase, iOS would be relatively unattractive (and I don't think Apple would feel like it could pull this kind of move).
A large portion of what Apple does that's specifically targeted at developers these days is negative. The NDA, rules so broken they were never consistently enforced, arbitrary rejections, retroactively rejecting apps when they decide to come out with a competitor, etc.
Also, I dispute the claim that this rule change was "entirely predictable." Can you show me somewhere that you or anybody else predicted this rule change before it came to light?
