Yes! And thanks to missing app store features Apple has provided developers no way to set expectations for things like upgrade pricing. Not to mention in-app purchases which were another way to maintain the illusion of "free" apps among users.
The fact that subscription pricing is now seen as the solution is really sad because subscribing to an App is fundamentally different than buying one. In particular, transactions that used to be atomic - like buying an app or gifting an App to a friend - are now transient and come with all kinds of strings and commitments attached.
Today I could go home, fire up my 5 year old iPod touch, and still access all of its apps - and the data therein. In a subscription-based app economy I wouldn't be able to do the same after the first month!
