So, upfront CTF cost is gone. For developers in Apple's Small Business Program, there is a 0% 'acquisition fee', 5% commission (and if you ship on the App Store or use IAP, that bumps to 10%), +5% Core Technology Commission. Total 15%, same as today

If you're distributing outside the App Store, and you're in the SBS, somehow you've got to give Apple 5% of your app revenue.

If you're not in the SBS, you pay a 2% acquisition fee on all transactions, 13% commission to exist, +5% CTC. Total 20%
