It's hyperbole sure. But the fact is that Apple's refusal to add upgrade pricing goes directly against Omni's entire raison d'être. They release exquisitely detailed and full-featured apps, and they've been doing so longer than any OS X developer since their roots are back in NeXT.
The current App Store pricing devalues software, it turns it into a disposable commodity to be purchased and discarded. Apple is willing to sacrifice it's own pro apps to this devalued future because that's not where it makes its money anyway and it has some major scar tissue from being held hostage by the likes of Microsoft and Adobe.
You can say it's just another distribution channel, but it's obvious that the App Store is the future, and is by far the most convenient and recommended channel and that will only increase over time. Comparing it to something that is easily provided by third-parties like analytics is to miss the fundamental connection: Omni makes the type of software that App Store pricing makes impossible to create and maintain over time. If this continues the ecosystem will dry up, and the type of pro users who love Omni's stuff will all disappear as well. It's a bitter pill to swallow because they love Apple's tech, but the writing may be on the wall.
