30% is almost 1/3 of the app price! It is higher than income tax in most countries. It is stealing money from developers because their app is not successful due to being released on App Store, it is successful because it is a great product and people would buy it on whatever store it would be available. Developers were just unable to publish it in another store or use a different payment processor with lower fees.
