Wow it changed a lot since the last time I did it. I wonder it if has to do with the type of app or permissions it requests. Back then(10 years ago so way back then), payment was all that was required. You had to wait for some automated reviews and tests and potentially a manual one which could flag issues depending on the permissions you request but it was straight forward. Apple, on the other hand, always had a manual review and was quite strict in what they would accept.
