Sorry, maybe it wasn't clear in that last post what I see as the relationship to monetization for Nokia.

The relationship is that some skilled developers will develop interest and familiarity with the platform if they're able to do what they personally want with it first... and then, they're more likely to choose to leverage that familiarity for app development with broader appeal, maybe commercial, maybe not - but part of the app catalogue either way.

Something like that also applies to development groups too. If they have an idea they want to implement, their choice depends on which platform they can implement it on first. For apps that use features every smartphone has, Qt etc. are attractive options. But those are the sort of apps which can be ported easily to all platforms

For apps that do more innovative things that might distinguish the Nokia platforms (or whichever the developer chooses), deeper access to the system's internals is an advantage. (It's a matter of good software engineering and working with others to make sure that isn't abused.)
