I'm quite sure the App Stores and licensing fees make sense for small business software developers only for the short while that the current "there's an app for that" gold rush holds.

Then people remember again that there are many revenue models outside the scope of licensing. And with many of those Maemo Extras works just as well (or better!) than an Ovi Store would.

What application developers really need is a capable platform that is widely distributed enough to provide opportunities, but also open enough to allow experimentation with different approaches and business models. iPhone isn't that.
