"Thank you for being an iOS app developer. We understand that Basecamp has developed a number of apps and many subsequent versions for the App Store for many years, and that the App Store has distributed millions of these apps to iOS users. These apps do not offer in-app purchase — and, consequently, have not contributed any revenue to the App Store over the last eight years."

To me it is very very rude. And free apps do contribute to app store. And they do charge 99$ so APPLE should stop saying they have not contributed to revenue for 8 years they do have paid 99$.
