I have my doubts. Do they even provide any support for apps on the app store? At the same time they’re paing truck load to lawyers and are about to fork off 10-20% of their global revenue for playing a subborn teenager.
Apple spends less on supporting app developers than many app developers want, but spends more than nothing. If an end user uses Feedback Report, Apple will spend less time/money on the report than the end user wants (and less than I think fair) but again, it's more than nothing.
Personally I think you can lower the cost by just making it difficult on the end-users side. If you put a scary pop up and require the password and bury it in the setting then boom, grandma who doesn't know the difference between wifi and the internet won't have issues.
