It's not a reward for Apple. It's a discount to thank/compensate those who read about the iOS client being available when it wasn't.
The in-app purchases can be managed outside the app so probably this "discount" will be temporary.
Then again, it isn't a bonus because you are an iOS user but the fact that we had a broken promise.

They aren't making our jobs harder, we just want to make it up for all the people that have been constantly asking us about the iOS app.
The parallel sale does sounds good though, so thanks. :)
"We’ll probably include a bonus discount to users who upgrade via the App Store" Really? You didn't choose Apple, the users did. Please explain to me why it makes sense to reward people for making your job harder?
By all means have a sale, but at least run a parallel 'Thank you for using a dev-friendly platform' sale for android/laptop users.
