That's the pessimistic view. The optimistic view is that developers will be encouraged to consolidate their app into 1 free app instead of creating 10+ free versions and variations. The AppStore is overloaded with spam already so the proliferation of "bait and switch" will likely be a minority issue all things considered. In the end, it's really no different than offering a demo application and asking to pay $XX for full functionality. I suspect most developers will go this route over a-la carte "modules" considering $.99-2.99 per app is pretty well engrained in customer expectations.
