I missed the survey as well.
One of the reasons that I chose the iPhone is the managed and curated App Store. I like that there is one place, and one place only, to find apps. There are policies in the App Store that should probably be changed, but I am not at all bothered by App Store restrictions. As for the other questions:
Yes, there should probably be some government regulation of internal app stores. I’m not sure that we can trust for-profit companies with little competition from making nothing but benign choices. There likely should be regulation that farly protect the interests of consumers and developers alike.
I have no idea as a consumer if developers are treated fairly by Apple. My gut feel is that they are.
If side loading is allowed on iOS, I want to make sure that there is a way to prevent it on my iOS devices.
I have no way to know if the 30% fee (and 15% subscription fee after one year) is fair or not. As a consumer I think in most cases if the fee was reduced, developers would keep most or sometimes all of the extra. I do think that some of the fees and restrictions are ludicrous, namely trying to capture fees of items like Kindle books, Netflix or Hulu subscriptions, etc. - I am not subscribing to these services because Apple happened to show them in the App Store - I am subscribing to most services because I heard about them elsewhere. I also, however, worry that other companies will not protect the privacy of my transaction data for internal purchases - I like having as few places to purchase from as possible. As an example, I have a local newspaper delivered to me most of the year, but I am away from home during the summer, so I suspend my delivery. The newspaper has a decent iOS app so I can read the paper during the summer, and I can subscribe using an in-app payment in the App Store. I could also subscribe through the newspaper itself, but when I did this last year, I spent half an hour on the phone trying to cancel my subscription when the summer was over. From waiting for a customer service rep to answer to refusing several offers to continue the subscription before they would finally process the cancelation, it took that long. In the App Store I will just click a button to stop the ongoing renewal and I will be done. There is a something enjoyable about such a simple interaction.
I would prefer that there not being multiple app stores on iOS. One concern is that specific apps might become exclusive to particular app stores, meaning that setting up a new device from scratch would require having to remember which app came from which store. As I said previously, I also trust Apple to keep my purchase history more private than I would other companies. I also worry about something like an app becoming exclusive on one store and then becoming exclusive on a second one at a later period. Would that mean that I would have to re-purchase the app from the second store? Personally I like the fact that there is one place to find apps, and I think Apple has done a decent job with it.
Lastly, and for what its worth, I really don’t want a huge number of apps anyway. I really don’t use more than a couple of handfuls of apps, and some of them are installed mostly so I can get notifications from them (e.g., from my bank to get a notification of questionable charges, etc.)
