I suspect the above poster was referring to the fact that Apple doesn't allow developers to have upgrade pricing. Developers instead must either switch to subscription pricing or release a new app "Tweetbot 5" which resets the apps review count.

It would definitely be nice if Apple allowed developers more flexibility in terms of pricing models.

(I suspect you know this, just wanted to touch all the bases)

I was aware of what you just explained, and it’s a complaint I agree with.

However the line I quoted was complete and utter bullshit. Apple does pull apps for very questionable reasons, but this is definitely not one of them.

You are spot on.

The original comment was so oddly worded, I'd assumed the other poster had mis-spoke.

I'm surprised I haven't seen more developers go for the 'Paradox DLC' model of putting large new features in IAP with a single ongoing base app.
