Tristan Kosmynka, one of the heads of the App Store, said that in 2017-2018, developers of 5 million applications applied for publication in the store. Approximately 40% of them were unable to pass moderation due to a violation of Apple‘s privacy policy. For example, in 2019, out of 4.8 million applications, slightly more than 1.7 million (36%) were refused publication.
Only 1% of developers usually try to challenge Apple’s decision.
